Hearing aids are very delicate devices that need proper care and maintenance, otherwise it might backfire on you. If you have been experiencing feedback sounds, such as whistling, quite often from your hearing aid devices, do not tolerate these noises. It’s high time that you need to change them. It is quite annoying and in fact, harmful for the hearing aid user. In such a case, instead of treating your hearing loss, hearing aid devices with annoying whistling sounds might even damage your overall hearing health. Are you paying for making your hearing health grow more adverse?
Health Issues Caused due to Untreated or Improperly Treated Hearing Loss
Now you may ask the most obvious question, “How is my hearing health going to be affected due to feedback sounds arising out of hearing aid devices?” Untreated or badly treated hearing loss can have a negative effect on the brain. This is to say, that if the sound processing (auditory) centre of the brain is not properly stimulated with all kinds of sounds, then a time may come, when the brain will forget the sounds it did not hear properly for a long time. As a result, it would not recognise those sounds, and the person might eventually suffer from Auditory Deprivation. Studies show that a person suffering from Auditory Deprivation for a long time would gradually develop the risks of Dementia - a condition in which the affected person suffers from mental disorders like anxiety and forgetfulness. All these issues will lead to social isolation and loneliness. So it is extremely important for you to not only treat your hearing problems on time, but you should also wear your hearing aid devices properly.
Causes of Feedback Sounds
There can be many causes of feedback sounds arising out of your hearing aids, the most obvious being -
Improperly fitted ear mold or shell.
Excessive accumulation of earwax in your ear canal, for which the hearing aid devices are not in their proper place.
Another astonishing reason of feedback sounds is when the ear mold of the listening device is pointed in the wrong direction, that is, instead of being pointed towards the eardrum, the mold is pointed towards the walls of the ear canal. This causes the sound waves to strike hard against these ear canal walls, thus creating feedback sounds.
Some internal damages in the parts of the hearing aid devices might also result in acoustic leakages and the production of feedback sounds. This may include hole in the ear mold due to rough cleaning.
How to Fix It?
Too much accumulation of earwax might block the ear canal, and this has become the major cause of feedback generation from your hearing aids. While sound waves leave the ear mold, they get reflected back from the solid walls of the earwax and if the mold is fitted improperly the sound leaks out and thus they create disturbing whistling sounds. It is very similar to a hose pipe spraying the water all over the garden, in all directions. Hence, it is very important for you to consult an ENT Specialist to get your ears cleaned of any excessive earwax and dirt.
Another common reason of feedback sounds is loosely fitted hearing aid devices. In case of children who are at their growing stage, due to the growth of their ear canals, their hearing aids become loose. So it is very important to change the ear mold of your hearing aid devices from time to time so as to make them properly fitted in your ears, and not experience any annoying sounds. Also, these annoying feedback sounds affect the user’s listening experience tremendously, as a result of which the person might altogether lose the interest to wear hearing aids. Not wearing hearing aids might in turn have adverse effects on the hearing impaired person.
A complete solution to all the above problems is to opt for digital hearing aid devices, which not only take care of these issues but also have a feedback cancellation technology. These are custom made and easily adjustable user-friendly devices, wearing which you will feel comfortable.
In a nutshell, always wear custom-made hearing aid devices, that fits properly in your ear. Never compromise on listening devices, as a wrong decision might make situations adverse. However, always keep in mind to consult a trained Audiologist before arriving at a final conclusion.
