Your hearing...........how good is it?
in another thread there is a little confusion about what humans can and can't hear or what their hearing range is. The link below will explain, to any confused, what the hearing range of humans is.
http://www.sfu.ca/sca/Manuals/ZAAPf/r/range.html
The link below you can test your hearing.

how'dja do?

My hearing is damaged in my right ear. This test shows just how bad, the curves are totally different on the right and left. Years of power tools and playing bass on the left side of the stage...
I always wonder how much my lopsidedness affects things. I am in the habit of wearing headphones backwards half the time to try to avoid compensating in the mix.

schwa, what is the difference from the good side to the bad?

dB threshold diffs left vs right:
60 : 3
3500 : 3
12K : 24
Can't hear 15K at all in the right. Sad.

Yeah, but why would you wanna hear 15k in the night? It'd keep you awake with all those pesky mosquitos buzzing around, especially in the summer. Average hearing levels depend on THRESHOLDS, ie, how loud it is at different freqs. You CANNOT test that with a pair of phones and an internet site. You need a trained audiologist and very expensive accurately calibrated hearing test equipment. And even then, the tests usually only go up to about 6k, within the range of speech, not hi-fi music or mosquitos. Needs to be done in a soundproof anechoic room too, or it means nothing. I know, my dad is an audiologist. Pardon? What was that you said? Plus there are many types of hearing loss. In musicians it is usually high freq loss through standing too close to 100 watt marshall stacks. Irreperable unfortunately. Inner ear damage. But often it's middle ear infection, or even wax. Curable with antibiotics, but not too often, or you get immune to them. Audiologists test for 'recruitment', where you hear sounds in one ear through vibrations in you head from the other side. Then there's tinitus.

Reason: couldn't hear a damn thing.

This is a relative (not absolute) threshold @ frequency test. Quick & dirty, but not useless. It says my threshold difference left vs right is 3 dB @ 3500 Hz increasing to 24 dB @ 12K Hz.

actually we just did test on the internet. so, you can and although it is not scientific in the purest of terms if I can hear 10K on the internet I can hear it at your dads office!
if your dad is an audioologist you would know that human hearing goes above 6k.

Havig more time than I know what to do with at the moment I did this test.
While I did no math the graph turns out about like they showed in a crude sense. The fact that my graph is silimar means I'm normal. But the fact that I did all this means I'm not LOL!! That was fun thanks

That was kinda fun! I did the test at home using my Sony 7506s and running off of motherboard audio, so I'm guessing that some of the high frequencies were being combined with some artefacts. However, I also have the same problem as schwa (slight hearing loss in my right ear, probably due to listening to music way too loud with my headphones on only the right ear), and it was interesting to quantify it. I didn't bother to get exact numbers, but when listening to the 5k test it starts out apparently centered and then starts to pan to the left until it's hard panned at the end for me. Only at 5k though; other frequencies seems perfectly balanced all the way down.

You can generate sweeps and stuff in Reaper using MDA Testone vst, fwiw.

Or you could just take my very unscientific, but working JS:"Hearing Test".
So here is how it works:
1. Download the attachments
2. print out the grpah
3. load the JS FX
4. hit trigger [1] to start
5. as soon as you hear a tone hit trigger [1] again
6. mark the graph (that you hopefully printed out) at the aproximate place to the number that will be displayed in slider 2 (or let someone else do it, there should be enough silent time to do it yourself though)
7. repeat step 5 and 6 till you reached 20k and can't hear anything at all anymore
8. look at your filled out graph, smile, and be happy

Given all the loud music I've played sans protection over the years, I am very lucky. My hearing is good up to about 19k @100dB.
One thing to be cautious of with these online tests is your headphones. I'm guessing most of the folks on this board own a decent set, but if you're not hearing anything above 15k or whatever it may not be your ears.
[Flame suit]
To me, one of the most valuable things about a clinical hearing test, or even just about sweeping through the frequencies in general is to see how irrelevant the extremes really are in most cases. You hear people talk about humans being able to percieve supersonic soundwaves or whatever and about speakers that are accurate to 50k and the fact is, you could pretty safely bandpass everything at 47hz and at 12khz @ 30 degrees like the old RIAA mechanical rule and musically speaking, pretty much everything needed for everyday enjoyment woud be there.
[/Flame suit]
Cheers.

I completely agree with you yep: I haven't tested it, but I'm pretty damn sure that I can't hear much past 16-17khz or so, and what I can hear in that range is so quiet compared to other stuff that it's pointless.
As far as headphones go, I was always under the impression that the 7506s that I have are overly bright; I haven't done a lot of research, but I know that whenever I switch between them and the Mackie HR824s I have at the studio I have this burning desire to crank up the highs on the Mackies.

Cute. I designed this in my head this afternoon too (complete with the triggers). If JS writing to disk worked you could even have the effect write up the results. And maybe write up a prescription for timpanic membrane surgery as well. Or insert a ReaNinJaOtolaryngology plugin and have some bored 13 year old kid do your surgery via the internet (one measure delayed).
