Why SNHL is progressive?

[giftedlion]

I want to understand why it is progressive ? And Can we do something from preventing it to go more? Mine had progressed from mild back in 1994 to severe/profound in 2011?

I don't know the answer to your question, but I am in the same boat as you. Mine has progressed from mild to severe as well and my test results are as bad as yours. It sucks.

SNHL is like hair loss in men.My loss was 60 db at 14 . I am 36 now and my loss is 88-90 db.

That is an interesting way to put it. I never would have thought of it that way.

Sadly, that is not true, because products are available to help men regrow their hair. All we can do is wait for researchers to study stem cells and transplants on humans (they are working on mice right now) and hope eventually the FDA approves the procedures. I agree with everyone else here it sucks.

Answer for the original question: Cochlear hairs do not regenerate when they die.

I've heard that people who live in mountains have perfect hearing into their 90s.

That's not quite correct. It's more accurate to say that due to certain genetic expressions, the body is inhibited from regrowing the cochlear hairs. The capability is still there in the genome.

Nothing to help women that are balding I've noticed. For a while I thought I was losing my hair but fortuntely that proved not to be the case. If it was though I'd be up the creek without a paddle.

(90-60)/(36-14) = 1.4 dB/yr. Anybody know if this is high/low/medium for an industrialized society? And I guess it's freq. dependent.

It's also dependent on congenital factors. Some people have resilient hair cells in their cochlear, some don't. Sensorineural loss will vary enormously amongst those with those the same level of sound exposure.

Under the exposure of loud noise, the small connecting pads that connect the end of nerve fibres to the inner hair cells swell. Over time these pads shrink, in some people they will disintegrate more readily and the attached neurone will disappear. This may not initially be obvious from early hearing tests as other neurones attached to the cell will persist in providing the signal. Repeated exposure will destroy the function and leave the 4kHz notch in you hearing.

All I can say is: don't join the 'Drum-Line'.
