Hearing-aids are instruments to amplify the sound so that you hear well.
Microphone picks up the sound and converts it into electrical energy.
Amplifier magnifies the electrical energy
Receiver converts the amplified electronic signals back to sound
The hearing aid has a battery which provides power to the amplifier.
Analogue hearing aids use conventional electronics. A microphone picks up the sound which is amplified and then reproduced by a ‘receiver’, which is basically a very small loudspeaker.
Digital hearing aids use a tiny computer to process sound programmed to suit your particular type of hearing loss. Some digital aids can be programmed for different listening situations according to your lifestyle.
|Analogue Hearing Aids||Digital Hearing Aids|
|Convert sound into electrical signals that are amplified.||Convert sound to digital signals (data) that are processed precisely by a tiny computer.|
|Some are programmable for different environments||Can be programmed to suit each person’s hearing loss|
|Make sounds louder but may not discriminate between them||Suppress background noise so that speech is clear and distortion-free and easier to understand.|
|Usually less expensive||Usually more expensive|
Only people with serious hearing loss need hearing Aids.
The need for hearing aids is dependent on your lifestyle, if you are in situation where conversation is important, then even a mild hearing loss can be frustrating. Untreated hearing loss also means not enjoying some of the pleasant sounds or reducing quality of life.
Mild or even one sided hearing loss can affect children’s speech and language development and academic performance so they also need hearing aid as a timely.
Hearing aids make noisy places noisier or screech.
No, newer designs do a better job in increasing amplification when you need it, while not increas¬ing background noise. Everyone’s experiences and needs are different. But yes! Hearing aids end in a drawer if someone didn’t get a good fit, received a poor quality product, or did not get proper coun¬seling about how to use a hearing aid.
What will my coworkers think?
Untreated hearing loss is more noticeable than hearing aids. Responding inappropriately in conversation, Smiling and nodding your head when you miss or don’t understand what’s being said, makes your condition more apparent than the largest hearing aid. Other People may think it as some mental problem.
Will my hearing deteriorate on using a hearing aid?
No. Hearing aid use will not make your hearing worse. Rather some of the studies have shown improvement in speech discrimination & understanding after a regular use of hearing aid.
Hearing aid does not cure or increase hearing loss/tinnitus/giddiness. However hearing aid amplifies the background noise and has masking effect on tinnitus.
The hearing aid amplifies the sound making it louder and thus helping the brain to hear the sound.
A Perfect Selection of hearing aid and Fitting specific to your needs is very important for the hearing aid to be effective.
For hearing loss in both ears two hearing aids provide a more natural and directional signal to the brain and help to understand speech.
Ear discharge should be treated by medical/ surgical methods before using hearing aids.
Even with the best of hearing aids, some difficulty like sound discrimination and slight difficulty in presence of loud background noise may persist
