Hearing Test
Whilst googling a few definitions and things mentioned on the digital recording thread I came across this hearing test www.phys.unsw.edu.au/jw/hearing.html
I thought I'd give a try and here's my result
If anyone else gives it a go please READ the instructions I don't anyone going deaf as a result of one of my blogs!

Oh, I didn't have the nerve to do it Andy - not with all those red warning signs and disclaimers. I just feared my hearing might be worse after the test knowing me and technology - brave man, looks like you have a serious dip at one point !

Damn it Andy, my rack is all over the place. I knew it was bad, but I was hoping.
Interestingly, a friend played me one of those frequency analysis discs at his studio. I forget now which frequency it was in the upper reaches, but when it played, the ringing in my ears ceased. I guess it was simply canceled, but what a relief for a few moments, anyway. Gotta love rock 'n' roll.

Verity wrote "looks like you have a serious dip at one point" but she is totally wrong this time! The test results show ones hearing as an equal loudness test... in other words it marks you when the sounds sound as loud as each other - so that "dip" at 4K is actually good hearing relative to the test benchmark set at 1K! Andy's hearing below 1K falls away a little, drops further at 125Hz and then gradually falls off the scale below 60Hz... and he is good at the top end up to 12k! Pretty good ears Andy!

Yes, Satch has got right, that dip is actually an upside down peak :-)
The overall shape is quite typical for the human based on the literature surounding the page.
I was pretty pleased with the results, particularly that I could still hear the high frequancies at all after 20 years of gigging with drummers! The only down side of being able to hear up that end of the spectrum isthat televions (old ones anyway) still make that iritaing wine when they're line oscilator has got dusty....

Ah, the old 15.625KHz whistle!! (At least in Aus on a PAL system anyway). :-)
Another bump to Satch too. What you'll also see in these graphs to a certain degree is the combined response of your hearing, the PC soundcard, your headphones and any ambient background noise. The better your soundcard and headphones and the lower the ambient noise, the more accurate the test will be.
