This may be of interest to some. I have no association nor have I tried it yet.

Well, it proves one thing, a large amount of the frequency response that my equipment can reproduce, according to the specifications, is wasted on me.

With my headphones I can hear down to around 25Hz, but only up to around 9000Hz with my right ear and around 7500 with my left.

Who needs headphones that can do 10 - 39,500 Hz? Not me apparently.

I can just make it to 15Khz.

However, maybe the computer isn't reproducing sound up there? Well that's my excuse anyway.

Is there a fixed way of using this test for your hearing?

The way I did it would mean mine is almost perfect, which i don't believe.

Although it did show a black spot in my left range, which I am already aware of.

I thought I was the only one who didn't know how to set it Chris!

Using the volume control on my amp I could hear wonderfully up to about 16khz, no way in real life.

And what about the db setting?

Human ears are less sensitive at the frequency extremes, so you may be able to hear 16,000 Hz, but it will need to be louder to seem to be the same volume as 1,000 Hz.

Here's a test with which you can determine the frequency response curve of your own ears: www.phys.unsw.edu.au/jw/hearing.html

Owen,

Don't know why but I can't get any sound off that site.

I tried another

www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/

This sort of confirms the result from the first site, on this one I have super human hearing 19khz.

Can't be right I'm 45 for pete's sake and have listened to loud music most of my life, attended countless rock concerts, done all the usuall clubbin' and played drums. I reckon it's all bow-locks...

Using the www.noiseaddicts.com link by cj I was able to hear the 8/10/12 and then jumped to 20/21. The rest I did not hear, weird if you ask me.

My hearing was damaged when I was a kid by repeated ear infections, which left me with scarred eardrums. Later I grew out of the ear problems and my hearing did recover to a large extent but tests I had as a teenager showed that I lost a couple of thousand hertz off the top end.

My hearing loss is a result of physical damage to the eardrum, which makes it less responsive, a bit like having a heavier speaker cone I guess. Damage caused by long term exposure to noise effects the tiny hairs in the ear canal.

With the ear canal type of damage it is possible to damage the hairs that respond to a particular frequency range, so you can get "gaps" in your hearing frequency range. You might be able to hear up to 18,000 Hz, but nothing from 3,000 to 6,000, where the hairs that respond to that frequency range have been damaged by long term exposure to excessive noise in that frequency range, perhaps from machinery, for example.

try it with different headphones too.
Some have really nasty dips at certain frequencies where SPL can drop 20 dB. at those frequencies
Also spikes of over 10dB can occur caused by resonances and break-up effects of the membrane.
an Orthodynamic can would be best suited.

how far up you hear might also depend on the listening level.

Set the volume to average level at 500Hz (or 1 kHz) and don't touch the volpot anymore and then try the higher frequencies.

I can hear upto 16.5 kHz and can detect 'pressure' to about 18kHz.
(use a tone generator, not PC based)
above that ... nothing... yet I know my HP can reach above it.
When I was in my 30's I could hear to 18KHz and detect pressure (at high SPL to almost 20 kHz)

One should realise the upper harmonics in audio signals (15kHz to 20kHz) are about 30dB below the mids and lows.
The tone generator puts out 0dB.
Try setting the level at -30dB for the higher freq and see if you can hear someting (don't be fooled by the click and knowing what freq. is 'set'.
Above 20kHz we are looking at -60dB (which already is almost complete silence compared to 500Hz)

tests where clicks can be heard at the beginning and end of the test tone can be ... deceiving (especially when you know what freq. is supposed to be there)

[mrarroyo]

What are the clicks for? I assumed they were not the actual frequency we were to listen for, correct?

Yes, I detect that 'pressure' but didn't count it as a sound!! You're kind of aware that something is making a noise but can't define the pitch easily.

Maybe there's 'break up' in my ears.

I could only hear up to 12K on Chris's link
