The Causes of Hearing Loss

November 21st, 2011 by Paul Minikin

There are many causes of hearing loss but the most common we come across as hearing aid audiologists is the general ageing process. Hearing loss is a natural consequence of getting older.

Our hearing starts to drop from our twenties and worsens from our thirties and forties. By the time we reach our eighties more than half of us suffer from significant hearing loss. Despite this a significant percentage of people with hearing loss are of working age due to other factors.

The next most common factor in hearing loss is exposure to excessive noise. We live in a noisy world and noise can come from our work or hobbies, such as using guns or listening to loud music at rock concerts, night clubs, discos and from stereos – with or without the use of headphones. The increasing use of portable MP3 players at levels so loud as to cause damage is increasing.
Hearing loss may also occur as a result of disease, infections or drugs. It may be inherited or be a result of physical damage to the ears or serious injuries to the head.

Hearing loss can either be conductive (related to the middle ear or ear drum) or sensorineural (related to the hearing nerve itself). Some people suffer from both, then we call it a mixed hearing loss.

What are the first signs of hearing loss?

October 8th, 2011 by Paul Minikin

By the time a client contacts us with a view to arranging a hearing assessment they have usually already accepted that their hearing loss is there and needs to be addressed, it’s become too much of a nuisance to ignore any longer.

There is a period of time before this decision is reached where the hearing loss gradually increases over time and the realisation dawns that things aren’t what they should be, this timespan can be months but is usually years, sometimes many years.

So what are the first signs of hearing loss, what are the early indicators that at some point your hearing might need to be checked? There are some quite common things that are noticeable, even before you start to feel your hearing levels have dropped;

  • Having a conversation in a crowded busy environment starts to become more and more difficult, the background noise becomes more prominent than you recall it used to be.
  • Often more softly spoken voices, particularly higher pitched voices like women and children, become disproportionately difficult to hear.
  • People seem to be mumbling more than they used to, clarity of speech seems to diminish somewhat and you may ask people to speak more clearly or look at you when they are speaking.
  • Your friends and family may start to comment that they think you may have a hearing problem, often those around you notice you have a hearing problem before you yourself notice this!
  • You may tend to want the television or radio turned up higher than others in the house or have a tendency to turn the volume on the TV up and down a lot.
  • You may find you have to concentrate more when listening to conversations, particularly in challenging environments, and this you may find tiring.

If these points sound familiar to you, maybe you should consider it time to arrange a hearing assessment, we offer hearing tests and good advice UK wide, the advice is free of charge and in most cases we offer home visits.

Your trouble with hearing could be due to excessive wax in the ear canal, it usually isn’t but part of what we do on a hearing assessment is to inspect the overall health of your ear and ear canal, that includes checking for excessive wax in the canal. We can advise you either way.

If you’re thinking about it we advise that you just pick up the phone or drop us an email, you’ve got nothing to lose and lots to gain!

Not just people but clownfish are losing their hearing too

July 11th, 2011 by Paul Minikin

The Clownfish, made famous by the Disney movie Finding Nemo, has been found in some cases to be suffering from some hearing loss due to the increase in CO2 levels in the oceans.

A recent study by the School of Biological Sciences at Bristol University showed clownfish reared in CO2 rich seawater seemed to be unaware of warning noises similar to predators in the wild when the level of CO2 was raised to where it is expected to be at the end of the century.

These fish rely heavily on their sense of hearing to detect the prescence of predators and also for their foraging and pack hunting capability, also for the recognition of a potential mate. With any one of these important skills missing it would not bode well for the clownfish.

The study conceded the fish might be more stressed and this could explain the change in behaviour, but anyway all might not be lost; the changes in the oceans CO2 levels due to fossil fuel emissions are happening slowly over decades so the fish hopefully have time to adapt. Like any such changes there are winners and losers, coral reefs are struggling to cope with the ocean’s rising acidification but seagrass based ecosystems are doing really well.

Go on a diet and delay age related hearing loss?

July 4th, 2011 by Paul Minikin

A recent series of experiments by the University of Wisconsin-Madison in the US has been shown to delay age related hearing loss in mice by reducing their intake of calories.

The experiments have shown that a 25% reduction in calories activated an enzyme (Sirt3) which helped to preserve hearing.

The professor of genetics Tomas A. Prolla stated ‘If we can find compounds that activate Sirt3 we may be able to obtain some of the benefits of calorific restriction without having to restrict our calories’.
