Hearing aids are devices that amplify the sounds for better hearing of a hearing impaired individual. These are small electronic devices that can be worn inside or behind the ears.
They cannot restore normal hearing but these wonderful devices can definitely improve the hearing experience of a hearing impaired person. The newer designs are smaller, more compact and more convenient than the older ones.
However, like any other device, it has its own set of drawbacks and disadvantages. It can have some serious side effects which need to be considered before opting for its use. Some side effects of using a hearing aid stem from improper use and loose fitting designs. These are temporary and can be corrected with proper usage and better designs. However some serious side effects may result from long term usage and therefore need to be addressed.
5 Side Effects of Using Hearing Aids
The loose fitting hearing aids may be uncomfortable for the person wearing them and can lead to some degree of soreness in and around the ears. However, this problem can be solved by wearing a secure and better fitting design.
A hearing aid picks up wind noise and other disturbances and amplifies them leading to annoying feedback sounds. However, this problem too can be rectified by the use of hearing aid liner which can effectively eliminate the feedback noise. This liner is easy to wash and clean and quite comfortable to the ears. Since it is soft and flexible, you can shape it with your fingers for the most comfortable fit and reuse with ease.
Poor Sound Quality
The hearing aid is designed to pick up high intensity as well as low intensity sounds. The high intensity sounds may be amplified further by the hearing aid to produce a screeching sound which can be very annoying and harmful for your ears, whereas the low intensity sounds may not be picked up by the device and hence remain inaudible. Each hearing aid needs to be adjusted according to the user.
Headaches and Tinnitus
The loud sound levels entering the hearing aid are further amplified to even higher levels that may cause pain in the ears and headaches and even tinnitus. To reduce this problem you should avoid setting the internal controls of the hearing aid on too high. The loudness level limiter should be adjusted as per the individual need to prevent very high sound levels from falling on the eardrums.
Cause Further Damage to the Ears of Severely Hearing Impaired
A severely impaired individual may not actually benefit from a hearing aid in the long run as he does not have a higher threshold of pain to bear uncomfortable loudness levels. The lower sound levels may not be audible to him and the highly amplified sound levels can cause further damage and even loss of residual hearing.
However, this problem can be corrected by the use of high power hearing aids which have adjustable maximum power output control. With the output control or loudness level limiter you can adjust the intensity of the sound waves falling on your ear drums to some extent and hence control the damage.
