You may be shopping for hearing aids for yourself or helping a parent choose the right hearing aid. For whatever reason, shopping for hearing aids can be tricky. There are a variety of styles, sizes and features available and knowing which questions to ask will help you pick the perfect hearing aid for you or your family member.1. Ask whether the hearing aid you want is best for your hearing loss. Although you may want aid that is completely in the ear, if your doctor or hearing specialist says that your hearing loss is profound, this probably isn’t the best choice. Don’t sacrifice your ability to hear because of vanity. Some hearing aids aren’t designed to amplify enough to overcome severe hearing loss. Others are particularly well suited for this type of hearing problem.2. Ask if the hearing aid has a noise reduction feature. This is a newer technology in hearing aids that allows for “noise reduction” that muffles background noise and interference. This allows you to more clearly hear speech without it being drowned out by background noise. This is achieved through a digital noise reduction circuit that reduces the amplification to cut down on background noise.Noise reduction can be a particularly nice feature if you frequently dine out or attend events where there will be lots of background noise. By essentially “turning down the volume” on the background sound, these hearing aids provide users with a more comfortable listening environment.3. How many bands or channels do the available hearing aids offer? In general, the more bands or channels a hearing aid has, the more finely tuned it will be to pick up and enhance sound without distortion. Multi-channel compression will split sound into several parts, using a different frequency for each region of the hearing spectrum. With the right compression applied to each channel, volume levels are fine-tuned and then the signals across each channel are recombined. If you vary in the amount of hearing loss you suffer from, which most people do, a multi-channel hearing aid may be a good choice.4. Ask if there is feedback cancellation on any of the company’s hearing aids. No one likes to hear the high-pitched whistle of a hearing aid that is experiencing feedback. If you’re the person wearing the hearing aid, the screech you hear can be painful, so more and more hearing aids today feature feedback cancellation to prevent this irritating and loud sound.5. Ask if the available hearing aids have noise smoothing technology that controls sharp noises such as dishes clattering and doors slamming.6. Make sure you ask about directional microphones in your hearing aids. These tiny, finely tuned microphones are designed to pick up sounds in front of you while minimizing sounds behind you. There is no other feature that will help you more with hearing in noise. It’s ideal for church services, noisy restaurants and other situations where you want your hearing aid to focus on the person you’re conversing with or your television program you’re watching, not what is going on behind you. Directional microphones are not available on all styles of hearing aids.7. Ask about the whether your hearing aid has a volume control or a remote control option. For some patients this can be a very valuable accessory because sometimes they find the hearing aids are not loud enough or too loud. A volume control provides a very easy to use remedy. Patients with dexterity issues may not want this feature.8. Don’t forget to ask if any of the hearing aids you’re considering are covered by a warranty. Most reputable hearing aid providers offer a warranty that will cover most, if not all, of the parts in your hearing aid for a year or longer.

Our five senses give us the ability to enjoy the daily beauty that surrounds us. The value of hearing, seeing, smelling, tasting and feeling are often taken for granted until one or more of those important tools start to deteriorate in some way. The ability to hear, as well as to see make life experiences more rewarding and certainly more enjoyable. The partial loss of hearing dramatically changes how life is perceived and choices that were once made quickly, become an effort due to hearing loss. Hearing aids have been around for centuries in some form, but most people found them bulky, burdensome and annoying. People who decided to use expensive custom fitted hearing aids, found themselves waiting weeks for it to be ready and then it would have to be adjusted from time to time, in order for it to function properly. New technology in hearing aids has solved those problems by introducing instant-fit hearing aids. Instant-fit hearing aids are usually in-the-ear hearing aids although they don’t have to be. They are manufactured using an automated assembly system and are built with standard housings and are covered with soft flexible ear tips that vary in size. Instead of customizing the hearing aid in the factory, the instant-fit hearing aid is customized in the hearing specialist’s office. Instant-fit hearing aids have been going through the development stage for the last ten years. The first step was to create digital programmable aids, which allowed the hearing specialist to adjust the electro acoustics in the office. The next step was using pre-made cores and soft sleeves which eliminated the need for the costly hard-plastic hearing aid shells. When those two steps were achieved, the hearing aid specialist could adjust and fit the hearing aid in the office and that eliminated the need for the manufacturer to get involved after the hearing aid was produced and sold. Purchasing an instant-fit hearing aid is like buying off the rack clothing. Minor adjustments might have to be made after the purchase, but the cost advantage is greater than buying custom made clothing. The instant-fit technology in hearing aids is here to stay. Manufacturers are improving their quality and performance. Consumers are taking advantage of their lower retail price. Custom hearing aids will still be important in the hearing loss market, because not everyone has a normal size ear canal. If the ear canal is abnormally shaped or is very small, a custom hearing aid with a factory customized shell is the only option at this point. If the ear canal is a normal size, the choice between a custom fit or instant-fit hearing aid comes down to where the consumer wants to spend the money. An instant-fit hearing aid’s digital signal processing devise can be put into a custom made hearing aid, but the cost is much higher. Some instant-fit hearing aids also have ear tips that are disposable. These ear tips have been designed to collect cerumen and as long as the consumer has the ability to change the ear tips, they are another option. The disposable ear tips may be less expensive in the short term, but for long term use a non-disposable instant-fit hearing aid is still the better choice. Instant-fit hearing aids will continue to improve and drop in price as the technology advances. With all the development taking place in hearing aids, the designer versions of instant-fits must be just a sound away.

Autoimmune inner ear disease (AIED) is an incendiary circumstance of the inner ear. The reason of AIED is mostly assumed to be related to either antibodies or exempt cells that induce harm to the inner ear. There is evidence that genetically controlled aspects of the immune system may increase or otherwise be associated with increased susceptibility to common hearing disorders such as menieres disease. It seems that allergies can cause or at least are associated with autoimmune inner ear disease. Observation suggests there is a genetic component as autoimmune diseases seem to cluster in families. Interestingly, this trait may show up as several different autoimmune diseases within the same family. However, this genetic predisposition alone does not cause autoimmune diseases to develop. Other factors need to be present as well in order to initiate the disease process.

Autoimmune inner ear disease is a rare disease occurring in less than one percent of the 28 million Americans with a hearing loss. Both allergy and traditional autoimmune disease such as ankylosing spondylitis, systemic lupus erythematosus, Sjoegren’s syndrome, cogan’s disease, ulcerative colitis, wegener’s granulomatosis, rheumatoid arthritis, and scleroderma can cause or be associated with AIED. The condition has been suggested to be more common in female patients who may or may not have concomitant systemic autoimmune disease than in male patients. Autoimmunity occurs with loss of homeostatic control in the immune system. Host tissues become recognized as foreign and induce damaging vasculitis and fibrosis. Veldman described a continuum of autoimmunity. On one end, organ specific responses with organ specific autoantibodies and T cells produce tissue alteration.

The symptoms of autoimmune inner ear disease are abrupt hearing departure in one ear progressing quickly to the second ear. The hearing departure can advance over weeks or months. Vestibular role may be lost gradually so that intense symptoms do not happen, but patients may produce ataxia and unsteadiness more evident in dark with long-term, multilateral vestibular hypofunction. More experience with the disease has revealed this to be a rare finding and it is not considered a routine occurrence in the syndrome. Outer Ear symptoms that may be attributed to allergy include chronic itching or frequent infections of the ear canal. Meniere’s disease in one or both ears may sometimes be aggravated by allergies. Diagnosis of autoimmune inner ear disease is difficult and is often mistaken for otitis media until the patient develops a loss in the second ear.

There are several protocols for treatment of autoimmune inner ear disease. Treatment goals in autoimmune inner ear disease include improving speech thresholds to levels treatable with hearing aids in severely affected patients and recovery of hearing to near normal levels in those with mild to moderate losses. Most patients with autoimmune inner ear disease respond to the initial treatment of steroids, prednisone, and methotrexate, a chemotherapy agent. Some patients may benefit from the use of hearing aids. In persons with response to steroids, in most cases a chemotherapy type of medication such as cytoxan or will be used over the long term. The medicine can be put right into the inner ear under local anesthesia, or through the use of tiny ear tubes put in place surgically. Not all people respond to steroid therapy the same way. Treatment in some people results in better hearing, or better discrimination or both.

If you are experiencing unusual sounds in your ears like hissing or swishing that comes from the inner part of your ear, then you are suffering tinnitus. Tinnitus is not a serious case or disease but an annoyance as it may cause agitation, disturb concentration or distract sleeping. This is why it is a must that it will be given immediate attention. There are a lot of possible treatments for tinnitus. Here are the three effective steps that you could use to free you from suffering for good.Click Here For Banish Tinnitus Instant Access Now!First, you must seek advice from a physician in order to diagnose and confirm the presence of tinnitus. The physician will determine if you need to seek further help from an audiologist based on the seriousness of your condition. Try to provide your physician all the information especially on the kind of noise you are hearing. Your first consultation is definitely not the last, so continue having a regular check-up with your physician.Second, you should consider having a cochlear implant or using a hearing aid. For the most part, hearing aids are claimed to be effective but one can also try electrical stimulation. The electrical pulses reaching the auditory nerve may reduce the symptoms associated with tinnitus.  It is important to know the review of audiologists on each individual as he can classify certain treatment for tinnitus based on the severity of the condition. Lastly, you can also go for an alternative tinnitus treatment. There are many ways and products that are available online. Look for methods that could help stop the ringing in your ears or search for herbal treatments like gingko biloba that is believed to reduce tinnitus.Usually each treatment for tinnitus will undergo a trial and error process to finally identify what exact treatment will work for you. It is important that you will not get tired in ending your suffering and banish tinnitus for good.

Tinnitus Miracle Cure

The reason Unitron Hearing is so revered is because they are tacking the issue of hearing deficiencies from all angles. They are making it easy to understand, handle, and prevent hearing loss.
Unitron Hearing recognizes this problem and fights it at every angle possible. They preach prevention as much as they practice resolution. This is what makes them such a commodity to a world that has estimated one in ten people suffering from hearing loss at some point in their lives.
They touch on every aspect that surrounds this problem from hearing aid repair, batteries, and devices. They specialize in making people more comfortable and less sub conscious in regards to having this issue. This company is a credit to this field and should be researched if you are diagnosed with deafness.
Hearing aid repair is something that many people don’t think about when they are getting their first hearing assistance device. It just seems to elude our minds when we are overwhelmed with having to deal with hearing loss in the first place.
Unitron Hearing realizes these are things we do not want to deal with and it’s why they stress the matter of prevention as much as anything else. We don’t stop and think about what noise is doing to our ears until something goes wrong. They bring these issues to light and try to get people to understand the nature of what we do regarding noise levels.
This company knows that dealing with things like hearing aid repair is not something we want to spend our time or money on. So shedding light on prevention is the next best step to treating it.
We all succumb to events and places that are going to damage our ears over time. Unfortunately, we do not feel the effects of things that damage our hearing until it is too late. Some of these things you know and others would surprise you but no matter what knowing what they are is the only way to combat them.
This is why Unitron Hearing works to educate people on these matters. They explain how the human ears are only able to handle so many decibels at one time and makes it known we are damaging our ears without us even knowing it. These are not scare tactics, they are the simple truth that gets swept away under a rug during the hustle and bustle of everyday life on this planet.

You’ve known you’ve had a hearing loss for quite some time now and you finally get up the nerve to get your hearing tested. They tell you that you need a hearing aid and you cant help but think, Why did this have to happen to me?? Then they start telling you about hearing aids and use tons of terminology that just goes right over your head. Dont they know that you are in shock??! How can you make an informed decision about anything when you dont even know what they are talking about!?

There are hundreds of different hearing aids. It can be a very complicated world of technilogical terms. Sometimes those of us that work with hearing aids all the time can forget just how foreign they can sound to you. To make matters worse, the manufacturers like to call things different names, so they sound like something different. No wonder there’s so much confusion!

I am going to try to unravel some of the mystery for you. When you get down to it, there are really only a few terms you need to understand. These features are the ones that really matter, and the model or the style of the hearing aid.

There are seven primary styles of hearing aids: ITE, Half Shell, ITC, Mini Canal, CIC, BTE, and Open Ear.

In the Ear (ITE) ITE hearing aids are the largest custom style of hearing aid, filling the bowl of your ear, and can have the most power and features available for in the ear hearing aids.

Half Shell (HS) The Half Shell is a custom hearing aid that only fills about half the bowl of your ear. They are able to have a good deal of power and features, use a smaller battery, but are more cosmetically appealing.

In the Canal (ITC) The next smallest size is the custom ITC hearing aid. Harder to see than the larger hearing aids, but also not able to have as much power or as many features.

Mini Canal (MC) Smaller than the ITC hearing aid, the custom mini canal uses a smaller battery and has even less power available. Features can also be more limited.

Completely in the Canal (CIC) The CIC is the smallest custom in the ear hearing aid and very popular due to its cosmetic appeal and ease of use. There are usually no manual controls on a CIC, telephone usage is often better because they are less likely to whistle. Lack of power is the main reason people cannot use this style of hearing aid, though a small ear canal may keep you from being able to wear one also.

Behind the Ear (BTE) A BTE hearing aid sits behind your ear and is connected to your ear by a tube with an earmold attached. BTE hearing aids have the most power and features available.

Open Ear (OE) and Receiver in Canal (RIC) This hearing aid is a fairly new style of BTE made available in recent years and are much smaller then a traditional BTE. They are meant primarily for high frequency hearing loss. The hearing aid is connected to your ear by a very thin tube or wire with a small earbud on the tip. They are called Open Ear because they leave the ear canal less blocked than other styles of hearing aid.

Important Features:

Directional Microphones – These are available on most BTE, OE, ITE, Half Shell, and ITC styles of hearing aids. They are the best feature you can have on your hearing aid for hearing in noisy places, such as restaurants. This means they reduce all the sounds that are behind you so that it doesnt get in the way of sounds that are in front of you. Directional microphones can be automatic meaning that the hearing aid automatically decides when to turn them on once the sound level in the room gets too loud. Some are also be adaptive, which means they can follow moving sounds, or reduce several different sounds at the same time.

Noise Reduction – Noise reduction doesn’t really reduce noise, it reduces amplification in the frequencies where there is noise and no speech. If there is a fan running in the background, the hearing aid will not amplify it as much as it will speech. When the hearing aid finds both speech and noise at a frequency, you still get both. More advanced the hearing aids manage noise better by breaking the frequencies up into smaller pieces.

Memories – There are two types of memories available on a hearing aid, manual and automatic. Many hearing aids have a push button that allows you to have different settings (memories) for different situations such as quiet places, noisy places, and music or telephone. The hearing aid beeps when you push the button to let you know which memory you are using. Advanced hearing aids can have memories that are automatic. Instead of pushing a button, the hearing aid does it for you! Some hearing aids have a combination of both.

Feedback Cancellation – Feedback (or that annoying whistling sound) is the number one compaint people have about hearing aids. Most hearing aid wearers experience feedback when they put their hand over their ear, or use the phone. Feedback Cancellation will take down the amount of feedback (whistling) that you hear.

Bands / Channels – Bands are what we use to adjust the volume in a hearing aid. More bands means more control when we program the hearing aid to your hearing loss.

Channels are used to adjust the part of the hearing aid that keeps the sound from getting too loud. Channels can also refer to the hearing aid noise reduction system. For noise reduction, more channels is definitely better because the hearing aid can break the sound up into smaller pieces and isolate noise from speech.

These are the main things you need to understand about your hearing aid. If you really want the best hearing aid for you I recommend you focus on telling the hearing professional what benefits you want from your hearing aid. Tell them what frustrates you most and give them a better picture of how they can help you. Their goal is to help you hear better, and when that happens, everyone wins.

Sound makes our life beautiful and fulfilling. For those unfortunate ones, cheap digital hearing aids are worth a look. Imagine, a world that is silent, where birds do not sing, where the sound of the running stream, the falling waterfalls is not heard; the musical instruments have no existence and you cannot hear what others are saying to you. It is unfortunate that around 10 percent of Americans are suffering from hearing loss, according to a survey by American Hearing Aid Association.
Though most common causes of hearing loss is due to aging, there are also several reasons which might lead to hearing loss such as excessive exposure to noise pollution as in a factory environment, birth related due to complications during pregnancy, or due to an injury leading to the bursting of the eardrum. In any of the mentioned cases, hearing aids are the ultimate source of hope to bring sound back into their lives.
There are different kinds of hearing aids which are advised by the physician based on your problem, budget, lifestyle and most importantly, on the one that is best suited to treat you. Of the three kinds of hearing aids – analogue, the conventional system, and digital, which is comparatively the new introduction, the basic difference between all is in their method of conversion.
Digital hearing aid converts sound waves using exact mathematical calculations that are processed by a computer, programmed in the hearing aid. There are several cheap digital hearing aids available in the market. You can purchase them either from over-the-counter stores or from online stores.
The only thing you need to decide before purchasing these life-enhancing products is to judge the authenticity of the product, as well as the reputation which you can find out by doing a search in google; and review the credibility of the online store or the dealer from where you are buying the product.
Before you make up your mind to buy them, make sure that you check out a few points which will determine if you are buying the right product. If you don’t you may live to regret it. The main functions of a digital hearing aid is that it translates sound to digital code, changes it and re-transmit it back by using mathematical calculations. More precisely to say, they duplicate sound transmission and produce high quality sound that is extremely accurate.
However, as the debate for cheap digital hearing aids continues, there is still a section of users of hearing aids who say they prefer the programmable analogue system of hearing loss aid over the automatic features of the digital hearing aid.

A revolution is afoot in the hearing aid industry. The stale and stagnant hearing aid companies have some new competition such as Zounds who have launched with revolutionary approaches and technologies aiming to help their customers hear better while not breaking their wallets in the process.Whether we realize it or not, we live in a world which is very much shaped by past revolutions. Regardless of the example, revolutions are bound to happen, especially when something is inherently wrong in the first place. Our founding fathers and their fellow colonists began to move away from the European monarchist ideals held by their British brethren, eventually standing firm on a new amalgam of republican beliefs of which can best be described as simply and uniquely “American”. Business monarchies still exist, but innovation is an ever-present revolutionary force. Kings of industry fall at the feet of innovators with a better idea. For well over a hundred years, Eastman Kodak dominated the consumer photography market and for much of this time, Kodak was the innovator. Kodachrome film, instamatics and disposable cameras were all the best ideas of their time and helped cement Kodak’s dominance, its monarchy. But Kodak became complacent. They ignored the trends of the very industry it created and ruled. By the late 1990s, digital photography began taking a large market share away from Kodak, which remained steadfast in its belief that film photography was the only good idea. Photography customers wanted a new, better idea and Kodak wasn’t responding. In what seemed like an instant, Kodak became an afterthought in consumer photography. The hearing aid industry has been operating the same way for decades and is not paying attention to the cries of change demanded by its customers. Hearing aid companies annually release sub-par products, which add to the overwhelming and confusing arsenal of products already offered. Additionally, these hearing aids are typically a repackaging of last year’s model with a new name and branded features which aim at deflecting attention to the over promised and under delivered elements such as noise and feedback cancellation. And what does the average customer pay for a high-end hearing aid? $2,500 to $4,000 per aid. And they still don’t work well. The new hearing aid companies are aware of the industry’s shortcomings and are revolutionizing the way hearing aids are manufactured and sold.There are 10 key challenges to choosing today’s hearing aids: #1: Hearing Speech with Mechanical Noise Any previous hearing aid wearer will tell you that despite how much he paid for that “revolutionary” technology, he still cannot hear conversations at his own table in a noisy restaurant. Look for noise canceling technology, which isolates unwanted mechanical noises, such as a fan or road noise, and electronically eliminates them. This is different than noise reducing hearing aids that reduce wanted and unwanted noise at the same time.#2: Hearing Speech with Human Noise The background “babble” noise of a busy restaurant can be enough to avoid eating out entirely. Yet, those suffering from a hearing loss often feel that they must avoid noisy environments such as restaurants, family gatherings, and social events. Look for a hearing aid with directional microphones that form a “cone of listening”, suppressing unwanted human noises and other sounds from behind and focuses on the sounds in front. #3: High Fidelity Sound Traditional hearing aids on the market are only programmed up to 5,000 Hertz. The range from 5,000Hz to 8,000Hz is considered the high frequency range and is where most hearing loss begins. It is also where the important consonants of speech, such as “t”, “ch,” and “s” are found. Be sure your hearing aid is programmed to cover the full hearing spectrum, up to 8,000Hz, so you can hear all critical speech consonants. #4: Eliminating Feedback We all know what feedback sounds like. We’ve been around our friends or family members when their hearing aids squeal. It’s embarrassing and painful. This all too common issue of hearing aids whistling or squealing is a result of feedback. Just like a poorly-tuned microphone at open-mic night, amplified sounds leak back into a hearing aid’s microphone and create a vicious cycle where noise is re-amplified again and again. Current hearing aids try to avoid feedback using a crude mechanical solution-shaping the hearing aid shell to form a tight fit in the ear canal, sealing off the ear.New hearing aids utilize sophisticated feedback technology that electronically isolates and cancels the leaked sound, thus eliminating feedback.#5: Comfortable Fit the vast majority of today’s hearing aids require a mold to be taken of the ear and ear canal. A silicon-based, taffy-like substance is poured into the ear canal. It hardens and then is sent to an offsite factory where the hearing aid is laboriously fabricated.The result is an expensive hearing aid that is uncomfortable to wear, causing perspiration and ear itch. New hearing aids use soft foam sleeves, which expand comfortably to contour the ear canal, absorb moisture and help eliminate ear itch. #6: Using The Phone Objects that are brought up to the ear cause an acoustic reflection. Too many of today’s hearing aids still squeal when a phone is close to the hearing aid, causing wearers to take out their hearing aids when using the phone. This is like taking your teeth out to eat. Look for feedback cancellation technology that electronically eliminates the acoustic reflection caused by a phone and allows owners to use a phone as it was meant to, up to the ear. In most instances, a telescopic (wired device connected from hearing aid to telephone) is not needed.#7: Reducing Occlusion A common complaint of hearing aid wearers is occlusion- the “plugged up” feeling resulting from the sound of your own voice vibrating within your head. The tight shells of today’s hearing aids are specifically designed to seal off the ear canal in an attempt to manage feedback. Occlusion is the unpleasant result of this approach. Hearing aids that use soft foam sleeves reduce occlusion.#8: Accurate Programming Conventional hearing exams are conducted using headphones, which have different acoustical properties than the hearing aids. In addition, they may only test 6 to 10 frequencies. New hearing aids use the hearing aids themselves as headphones and test and program the full 16 frequency band range, resulting in less translation and programming errors and fewer return visits. #9: Remote Controllable Traditional hearing aids offer their owners limited control over their devices. Wearers must struggle with little knobs on the hearing aid faceplate. The knobs are difficult to adjust and typically only control volume. The newest hearing aids are controlled by a handheld remote control. Sophisticated remote controls even allow users to adjust the volume, bass, and treble and chose among different listening environment presets.#10: Rechargeable Batteries Traditional hearing aids require replacement batteries. Those tiny batteries can cost over a dollar a piece and last anywhere from 4 to 6 days. Look for rechargeable batteries. Not only do these batteries provide more power to the hearing aid, they last all day and can be recharged in a complimentary charging station each night.#11: Virtually Invisible Hearing aids in the past were bulky, clunky, and frankly, ugly. New hearing aids are miniature, cosmetically appealing, and virtually invisible to others. They aren’t Grandpa’s old hearing aids anymore.#12: Reasonable Price Higher price doesn’t equal higher performance. Traditional hearing aids can cost between $2,500 and $4,000 per hearing aid. New hearing aids that use a combination of foam sleeves and sophisticated feedback cancellation allow significant manufacturing cost savings, which are passed on to the consumer. New hearing aids with this technology can retail for under $2000 per hearing per pair.Complacent hearing aid companies have pulled the wool over the collective eyes of their customers for too long. The mob has formed and shouted for change. These new hearing aid companies are making sure that these cries do not go unanswered. They are approaching the hearing aid industry with revolutionary approaches, technology and pricing, much to the delight of those who currently suffer from a hearing loss.

The most overwhelming factor for senior citizens of how a hearing aid works is the technology behind it. Most adults have a time embracing the fact that technology runs almost every gadget that helps us live by especially things that we ought to attach to our body for it to function accurately. Hearing aids are gadgets that have been here for years. The first ones are cone-like devices that you hold up to your ear so a person can speak into it. It works just like a funnel. Now that we are in modern times, hearing aids improved in degree of technology. All of them have the same parts and mechanisms. So how do hearing aids work?

First of all, hearing aids have microphones. Just like how normal microphones are, they make the sounds louder but in this case, a small microphone is being used. Sound that comes in gets transferred into digital signal and once it is transformed into data, it will then revert back to sound again but now in a much louder volume. There are hearing aid microphones that are set for a specific type of hearing loss and user environment so that one may customize or choose for their own comfort. There are hearing aids with a directional microphone, meaning, you may choose to only amplify sound coming from in front of you to help reduce background noise.

Most people needing hearing aids consult the help of Audiologists. These are specialists who concentrate on the needs of a patient. They would normally ask you questions to know more about what type of hearing aid you are looking for. Some questions may consist of the type of noises you hear, if you need to hear them, or the factors that prevent or help you from listening accurately. All these questions will prove to be very helpful in finding the exact adjustment for your hearing aid.

After you have answered all the questions, the audiologist in return will adjust the hearing aid based on the specifications like volume, and direction of the origin of sound. Still about technology, there are three types that receive and convert the signals in hearing aids. They are the analog which is adjustable, another is also analog but programmable, and the third one is the digital programmable hearing aid.

The Adjustable Analog is the cheapest of the three. This type of hearing aid, as how it is called, is adjustable by the audiologist as per the patient’s specifications. It will then be produced for you and you can either control the volume or have it automatically done. The Programmable Analog is another type of circuitry. These are somewhat better than the adjustable because it is programmed by the computer. Programs are used by audiologists to capture sound and transmit them into various listening scenarios. They are operated usually by a remote control and the user may select which program to use at any given time. Digital Programmable hearing aids, compared to the previous two, are more advanced in nature. It is also the most costly of the three. It contains a feature called DSP (Digital Sound Processing). It uses a computer chip to analyze the data before it is transmitted to the ear. It is also capable of detecting and eliminating feedback by identifying its frequencies. It is also user friendly.

One of the occupational hazards of living in the modern industrial age is noise exposure, both in and away from the workplace. Acoustic noise can be defined as unwanted sound and sounds louder than 80 decibels (dB) are considered potentially dangerous. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), more than 30 million Americans are regularly exposed to hazardous sound levels. According to the EPA the number of people exposed to work induced noise damage is around 9 million.
Noise is considered a necessary evil and the insidious effects of exposure above acceptable levels are generally not realized, mostly because there are no visible effects. The primary effect of excessive noise is hearing loss, either temporary or permanent, depending on the level and duration of exposure. What is even less well known are the secondary effects ranging from sleep disturbances: stress and fatigue, irritability, annoyance and lack of concentration. Noise induced lack of attention and the consequent loss in efficiency are matters of prime concern in the workplace. Not only is productivity impaired, but chances of accidents, impinging on worker and workplace safety, are also increased.
The federal Occupational Safety and Health Administration (OSHA) has developed regulations for acceptable threshold limits of noise in the workplace and mitigation of excessive noise. The 29 CFR standards 1910.95 Occupational noise exposure, lays down permissible exposure limits for different durations of exposure. The recommend exposure level, as per the standard, is 85 dB A on an 8-hour time-weighted average (TWA) basis. If this limit is exceeded, feasible administrative or engineering controls are to be utilized. If such controls fail to reduce sound levels within the permissible exposure limits, personal protective equipment (PPE) is to be provided. Further, irrespective of the reduction of noise exposure to 85 dB A or below with the use of PPE, the employer is to implement a hearing loss protection program.
The 1910.95 standard refers to the mandated hearing protection program as the “Hearing conservation program”. This program has five operational parts mandated: (1) Noise monitoring (2) Audiometric Testing (3) Employee Training (4) Hearing Protectors and (5) Record Keeping.
Noise monitoring
Sound levels in the workplace must be measured to ascertain which employees to include in the program, the need for hearing protection equipment and its suitability.
Audiometric Testing
All employees in the program must be subjected to a base line audiometric test to determine pre-existing hearing loss, if any. Annual tests are to be carried out thereafter to asses the effectiveness of the program and for appropriate remedial action as necessary. The standard specifically requires that the audiometric tests be carried out by duly qualified personnel under the supervision of an audiologist, otolaryngologist or physician.
Employee Training
All employees in the program must receive annual training on the effects of noise on hearing, hearing protection devices and the purpose of audiometric testing.
Hearing Protectors
Hearing protection devices must be made accessible to all employees in the program.
Record Keeping
Records of employee exposure (sound measurement), acoustic or exhaustive audiometer calibration, and audiometric test records must be updated. These records are to be maintained for specific periods of time.
Experience has shown that effective hearing loss protection programs are universally beneficial and that both employer and employees stand to gain from the programs. The employees are protected from hearing loss, fatigue and general debility. The employer benefits from improvement in employee morale and productivity and will also enjoy reduced medical and worker compensation costs.
