hearing test - equal loudness contours
Equal loudness contours and audiometry: http://www.phys.unsw.edu.au/jw/hearing.html
And if you just want to see how sensitive your hearing is to those high frequencies... http://www.noiseaddicts.com/2009/03/can ... ring-test/
edit: I can hear up 18kHz (the 18 actually sounds louder than the 17 to me), at 19-20kHz I don't quite hear it but it feels like a buzzing in my brain, at 21-22kHz I didn't notice anything but I started to get a light headache

On my work computer (read cheapest sound card available) and crap work issued headphones I can hear 17 but not 18. Do get the wierd sensation at 18 though. Get nothing from anything higher.

Would even "crap headphones" reproduce higher f's than 'crap' pc speakers?Mr Awesomer wrote:On my work computer (read cheapest sound card available) and crap work issued headphones I can hear 17 but not 18. Do get the wierd sensation at 18 though. Get nothing from anything higher.
Will big bands ever come back?

Found the specs on the headset I'm using: 20 - 20,000. If I'm reading the specs on the soundcard correctly, frequency response falls off quickly at 15,000... so it's either the soundcard... or my ears.Eyeball wrote:Would even "crap headphones" reproduce higher f's than 'crap' pc speakers?Mr Awesomer wrote:On my work computer (read cheapest sound card available) and crap work issued headphones I can hear 17 but not 18.

With Sennheiser HD 457 Headphones (25Hz-21kHz frequency response):
On my desktop PC at work (crap onboard audio device), I get the same as Reuben up to 17kHz, if I crank the volume I can hear to 19kHz and hear something at 20kHz but it doesn't sound like a 20kHz sine wave.
On my laptop (2 year old Dell Inspiron 6400 with SigmaTel audio onboard), I can hear 19kHz, if I crank the volume, I can hear 20kHz. I can hear something at 21 but it doesn't sound like 21 so it's likely some sort of distortion at the top end of the headphone's response.
Actually I think I can hear 22kHz with the same headphones and volume cranked on my Turtle Beach AudioAdvantage Micro but there is also a lot of distortion at 21 and 22, some distortion at 20kHz but notably more than the SigmaTel so I think at least some of it is due to the audio device.
My guess is the filter after the D/A conversion has a sharper roll-off with SigmaTel compared to the AA Micro. I'm curious, now I want to check out the frequency response with a proper function generator and oscilloscope.
Given the fact that I was a live blues events all last weekend, I'm happy my hearing recovered. 3 nights were right at the front, 2 of those were literally about 3 or 4 feet away from a trio of bass speakers.
