HF Hearing Loss

[JohnJo]

Borrowed a signal generator to test my system and inadvertently discovered I'm deaf as a post above about 12.5KHz

I'm not sure of the unit's calibration but my wife and children could clearly hear up to 17Khz. So even assuming the generator was 3KHz out (highly unlikely), and they could hear up to 20KHz, I'm still 4.5Khz down.

I guess that's 27 years in industrial maintenance for you despite being pretty careful to use hearing protection.

Thing is, I don't feel I'm missing anything, so what *am* I missing?

What sort of sounds are above 12KHz, on recordings or otherwise?

Eh, what?

You have slowly adjusted to the loss. Think frog gradually boiled rather than dropped into boiling water!

If you had lost your hearing suddenly you would notice.

BTW: The frog story is untrue!

Not much sympathy around here tonight then

Don't worry about it . If your above 55 it's completely normal . With age our HF hearing diminshes . I can hear to 14 k cycles and I could swear I'm hearing as I always have . Above 14 k all we have mostly are harmonics and even then most of the upper range of harmonics are lower the 14k cycles . If you can still hear a bright recording sounding bright your ok .

As a matter of fact my wife is 59 and can only hear to 8 k and even then she can hear subtle differences in the sound of my system when changing components

Did somebody say something?

I have hearing aids but still love music ! They were going to fit me a pigs ear but in tests there was a bit of crackling

Enjoyed that!
