Scientists are exploring new avenues for restoring hearing loss in adults.

Researchers have tracked a cell-to-cell signalling pathway that designates the future location of the ear’s sensory organs in embryonic mice. The scientists succeeded in activating this signal more widely across the embryonic tissue that becomes the inner ear.

“As the population ages, there’s a great interest in discovering how to regenerate the inner ear sensory cells that we need for our hearing and balance,” said Olivia Bermingham- McDonogh of the University of Washington.

“Both of these falter as we get older – we get hard of hearing and unsteady on our feet – due to accumulated destruction of the sensory cells in the inner ear,” she added.

The goal of their research is to develop ways to restore inner ear sensory hair cells in people who have lost them due to age, excessive noise or other toxic damage.

In order to devise a way to restart hair cell formation in the adult ear, Bermingham-McDonogh’s group studied how hair cells are made in the first place during ear development. They could encourage the formation of new building foundations throughout the inner ear. Once these new sensory patches were made, new hair cells and support cells were properly produced within them.

So by starting the ball rolling with the Notch signal, the researchers observed that the rest of the developmental processes followed along correctly.

The team is now studying ways of manipulating the Notch pathway in the adult inner ear to see if this will stimulate hair cell regeneration in the hearing and balance organs. If ways could be found to safely re-start particular Notch signals in adults, therapies might be designed to regenerate specific tissues, like nerves, and thereby repair damage and restore lost function, like hearing.

The findings are reported this week in the early online edition of Proceedings of the National Academy of Sciences.

A good workout in the gym is important for many reasons including you weight, muscle tone and lung and heart health but for those who listen to their mp3 player whilst working out they may be doing more harm than good.

A new investigation carried out involving subjects listening to the same music in three different places has had interesting results. The subjects were each placed in a quiet environment whilst resting, a noisy environment whilst resting and exercising on an exercise bike.

It is a proven fact that people are generally listening to their mp3 players at safe levels when the environment they are sitting in is quiet. When the background noise goes up it seems the volume level on the mp3 player is also turned up.

The new study highlighted the fact that people purposely increased the volume on their mp3 players when they entered an environment where the background noise levels were high. Working out in a gym was one place where people were frequently shown to be turning up the volume.

When you are working out in the gym there are many different sources of noise being omitted around you. Televisions, radios, the noise from equipment and general chatter all increase the background noise levels. Heavy breathing whilst working out also adds to the volume. Some of the participants also freely admitted that they increase the volume in order to pump themselves up at the start of a workout.

It is proven that people listening to music in a quiet environment choose to listen at a lower level as there are no other competing sounds surrounding them.

Some previous studied agree that the louder the noise in the background the higher people adjust the mp3 volume level to. Researchers discovered that whilst working out people turned the volume up to 75% of the capacity which leaves them at high risk of hearing damage.

Investing in a set of headphones that block out all background noise is a good way to ensure that you won’t be tempted to turn up the volume.

Deafness claims can be pursued via a qualified solicitor. Tinnitus Claims are also often pursued by people suffering from work place hearing damage.

The Vuvuzela is now a key symbol in the history of the 2010 World Cup in South Africa. The sound of the vuvuzela instrument was the topic of much discussion throughout and after the end of the World Cup. Although many people considered it to be seemingly harmless the vuvuzela does pose health risks. It generates an extremely loud monotone sound when played, one which has been an irritation for many football fans worldwide since the World Cup began.

The noise resulting from the Vuvuzela has been proven to cause hearing loss when the exposure levels are high such as during a packed football stadium of fellow fans all blowing on them. The noise alone was considered beyond irritating by many.

Charity Deafness Research UK have now discussed the Vuvuzela stating that; ‘The competition could also score an own goal – with football fans risking permanent noise induced hearing loss, from the constant use of Vuvuzela horns.”

Lots of South African football fans regularly use Vuvuzelas and are therefore used to the sound produced, the same cannot be said for the thousands of international supporters watching the world cup. Although many called for a ban on the Vuvuzela it was overturned as the instrument was said to be an important part of the African culture.

The deafening pitch created by the Vuvuzela can eventually lead to serious health problems relating to the ears which confirm the fears the fans present at the world cup had. Deafness Campaigners are now looking to prevent them from being used in future football and sporting events.

There is already many different risks to people in the UK regarding noise induced hearing loss, adding to it with the use of Vuvuzelas is not something health campaigners will be happy to let happen. Work place noise induced hearing loss is a common problem here in the UK, having the Vuvuzela present in leisure time could see many people suffering.

If working in a noisy environment has affected your hearing, then you may have a case for a noise induced hearing loss. Visit the What’s My Deafness Claim Worth site to learn more about how to begin anindustrial deafness claim.
