Are All Hearing Aids The Same?
- Last Updated: Sep 7th, 2018
If we see from the manufacturing standpoint, the answer will be ‘yes’. This is because every hearing aid consists of a microphone, amplifier, receiver, and battery. But if you compare the functioning and working of all hearing aid machines, the answer will be ‘no’. All the hearing aids are different in usage, technology, quality, and price. Every Hearing Aid have its own purpose. As we know there are 3 kinds of hearing loss –
In every hearing loss, a particular type of hearing aid is used.
Components of Hearing Aids
Microphone- It receives the sounds waves from the air and converts them into electrical signals.
Amplifier- The signal received from the microphone goes to the amplifier which increases the power of a signal.
Receiver- It converts the digital signal into vibration. This passes through the inner ear to the brain.
Battery- Battery provides the power to the hearing machine.
Different Hearing Aids and their Uses
There are mainly three styles of hearing aids-
Canal Hearing Aids
They fit inside your ear and are harder to see. Three types of canal hearing aids are- In-the-canal (ITC), Completely-in-canal (CIC), Invisible-in-Canal (IIC). They can help in mild to moderately severe hearing loss. This type of hearing aid isn’t ideal for children or adults who might have problems with very small devices
It fits completely inside your outer ear. Best for people with mild to severe hearing loss. They don’t work for the children whose ears are still growing.
It is covered in a hard plastic case behind the ear. It fits inside the outer ear and directs the sound coming from outside to the ear. A Mini BTE fits entirely behind the ear. And its narrow tube goes into the ear canal. This helps in building up of earwax and ensures that your own voice sounds clear. Anyone can use BTE hearing aids regardless of age and amount of hearing loss.
