Before understanding how hearing aid helps with deaf people, first let us see what it is actually. It is an electronic device that helps with hearing issues. This can be worn around ear according to the type that deaf people prefer. The aid makes louder sounds for the deaf people that help the person with hearing loss to listen, communicate and participate in all daily activities. The aid will help those people to get over the issue and hear both quite and noisy sounds. However the benefits of this device is not known to few people and there are people who are not aware of its uses. The hearing aid is actually designed with three basic parts like microphone, amplifier and speaker. The hearing aid helps in receiving sound through microphone and that sound is converted to waves which in turn sent to an amplifier. With the help of amplifier, the power signals are sent to ear through speaker. This is the simple working of hearing aid electronic device.
Hearing aid to certain hearing issue
Well, we have understood the basic working of the device. Now let us see how the hearing aid helps people. The device is helpful for people who are suffering from hearing and speech comprehension. Thus people with hearing loss have the useful effects which are resulted with damage to small sensory cells within inner ear called hair cells. As there are various types of hearing loss issues, above described is the sensoribeural hearing loss which needs proper treatment and can be recovered in the process. This type of hearing is the result of few disease, aging or injury due to noise or few other medicines.
As said before, the device magnifies the sound vibrations entering ear. According to Active Audiology, surviving hair cells detect the larger vibrations. This will convert those vibrations into neural signals which in turn passed to brain. When the damage to person hair cells is high, then it will result in severe hearing loss. The hearing aid is amplified with higher specification to make up the system. This will then make the difference in hearing aid. Even though there is a limit to use amplification severity. The amount of amplification used within the device is limited to certain wavelength. All these are possible only if the inner ear is not damaged too high. If the inner ear has issue, then a slight vibration would also be not effective.
