True or false a hearing aid solves the problem of been deaf and why?

Answer 1

For conductive losses (those that RTPye refers to) functioning hearing aids can restore hearing to within normal limits -- which is not quite the same as "solving" the problem of being "deaf" Hearing aids for conductive losses bypass the conduction problem that is causing the hearing impairment, and use the skull to simulate the cochlear nerve directly. If your loss is entirely conductive, however, you are not deaf. Under these circumstances, the maximum amount of loss you can have is about 55 dB, which is not considered "deaf". The generally accepted definition of "deaf" is a bilateral hearing impairment over 81 dB. Finally, there is the practical issue that if your batteries die or your hearing aid breaks, you are back to being hearing impaired. So hearing aids don't "solve" the problem of being "deaf" for conductive losses, as much as they temporarily restore ones hearing to within normal limits.

Most people don't have conductive losses though, they have
nerve based loss (known as sensorineural loss). Hearing aids for sensorineural loss work by amplifying sound. When you amplify anything, you distort it. There is a limit as to how much amplification you can apply to any sound signal. Furthermore, when you amplify the sound around you, you are amplifying ALL sound, not just the sound you want to hear. The more expensive digital hearing aids include all kinds of technology to try to suppress the amplification of the background noise that you don't want to hear, but it can only do so much.

Answer 2

False. The reason deaf people can't hear is because their eardrum does not vibrate. There are operations to fix this, but hearing aids don't help a deaf person.

Answer 3

False, a hearing aid improves hearing for those who have limited hearing. Those who are completely deaf will not benefit from a hearing aid.

Answer 4

False. No device is perfect and nothing matches the capabilities of the human body's natural functions.

Answer 5

It depends on the type, reason and severity of the hearing loss.

Answer 6

real--too a lot of human beings seem at a project and notice a occupation if not a earnings margin those days. they are here to apply and _exploit_ the subject for their very own earnings, not actually remedy it and help individuals.
