- A hearing-impaired colleague informs me that frequency-equalized
- hearing aids have been state-of-the-art for many years. He had his
- hearing analyzed and the proper correction was implemented in
- his hearing aid. As with most hearing-impaired, his response at
- the low frequencies is almost normal.
-
- On the matter of the cause of the impairment, my understanding was
- that it is commonly due to damage (or improper development) of the
- little hairs that pick up vibrations in that little shell-shaped
- thing (I forget the name). If the nerves were damaged, no amount
- of amplification would get the signal to the brain.
