Have you been in a situation where you had trouble hearing properly because water entered your ears or due to the presence of ear wax? What did you do? You’d either try to fix the situation yourselves or seek medical help immediately because it’s a huge relief when the block is removed and you are able to hear properly. Hearing, one of the most important of all the senses helps us to communicate with fellow human beings through speaking and listening. The loss of hearing could result in a feeling of isolation and the situation could be fearful too. Some people suffer from total loss of hearing since birth while some lose their hearing ability as they grow older. The invention of hearing aids has been a relief to many people who suffer from hearing impairments.
Reasons for hearing loss
When the passage between your brain and the outer ear is damaged or blocked in different areas or in a number of ways, you could suffer from full or partial hearing loss. The hairs inside the cochlea get damaged at times and this could result in loss of hearing and is referred to as sensorineural hearing loss. The stimulation produced by sound in your brain is much less when the hairs in the cochlea are lesser in number. This type of hearing loss is quite common and this is when hearing aid proves to be of great use.
Hearing aid and its help
A hearing aid is an electronic device that has an amplifier, a microphone and a speaker. It’s quite small and worn inside or behind your ear. The sound is received via the microphone and gets converted to electrical signals and sent to the amplifier which then increases the power of the signals and sends to the ear through the speaker. People who suffer from sensorineural hearing loss are the ones who primarily benefit from hearing aid. A hearing aid wouldn’t be effective if the damage to the inner ear is severe.
Different kinds of hearing aid
Analog hearing aid
In this type sound gets converted to electrical signals, signals get boosted and turned back to sound which is of higher frequency. Important sounds, as well as the noise in the background, get amplified.
Digital hearing aid
In a digital hearing aid sound signals get digitised, processed and filtered before amplifying them. Clarity and quality of the sound is excellent. It’s also capable of blocking noise that’s unwanted and emphasizing certain sounds.
Different types of hearing aid
- BTE (Behind the ear)
BTE has a hard case made of plastic (microphone, amplifier, and speaker) behind the ear which is connected by a tube to an ear mold which is a plug that can easily fit inside the ear canal.
- ITC (in the canal)
- CIC (Completely in the canal)
- ITE (in the ear)
