first off, I am 24 years old.

I was checking out my DVE audio tones and i did a frequency sweep from 15 HZ to 22kHz

It seemed like somewhere netween 15kHz and 17kHz I could not hear the tone anymore. I tried a couple of times, even got closer to the speaker and turned the volume up at that part a bit..... I just heard the 'hiss' from my tweeter that is there from the amp. I could not turn things up too loud because I found no way to only play the tones that I was having problems hearing. The ones I could hear would get pretty loud.

I checked out this web site:

http://www.freemosquitoringtones.org/

and I was able to hear the 19.8 kHZ tone loud and clear though.


I could just BARELY hear the 21.2 kHZ. And by barely I mean barely... if I didn't know I was playing something I probably wouldn't notice it.

Also I checked out this website (note: turn down speakers if you click on this link)
http://www.freehearingtest.com/test.shtml

and turned my speakers down as low as they could go so the test tone was barely audible. I was able to hear all test tones fine, but it only went to 8khz.

And here is one more:
http://deafness.about.com/gi/dynamic/off...jw/hearing.html

I was able to hear all the way up to 16 khz no problem.
I have no idea how close these sounds are to what the frequency says but I thought I would mention here and see if you guys thought I had hearing loss!

Also, the other night my girlfriend was sitting next to me and I was doing a 15 hz to 300 hz frequency sweep at a pretty low volume. She said she could hear the sound at about 21 hz, and I really had to strain to hear it. I could hear it easy as pie after about 25 hz. If I turned up the volume on the receiver I could hear the tone the same time as she could.

My girlfriend was at work tonight so I can't see if she can hear the high frequency tones on the DVE, since she apparently has really good hearing.


Anyway, so does my hearing suck? how high are the m80's suppose to be able to play?

terz,
Women hear better/are more sensitive than men at detecting high frequencies. I'm not surprised she can hear tones slightly beyond.
The typical upper hearing range for humans is around 20kHz, (give or take a few thousand).
I spoke with the provincial nurse during my hearing test that takes place in the little sound proof booth (part of getting SCUBA medical certification over the years) and she said that discerning frequencies correctly beyond 16kHz becomes unreliable and more variable (i.e., on average people she's tested start to fail the hearing test around 16kHz).

I can hear it up to 19KHz for sure with the 80s but I do have to turn it up.

The only way you can know whether or not your hearing sucks is by going for a test. So do yourself a favour and go for one so that you're not forever wondering in high anxiety. The 80s and a test CD are not the way to test your hearing.

I agree with Mojo, but will add one other small thought.

Remember: the way that the frequency scale works there is very little real-world difference between hearing up to 15K and hearing up to 19K.

The 4Khz between those points is NOT the same as if you were losing 4Khz between 6Khz and 10Khz for example....

I'm jealous. You have great hearing. I'm 54 and had my hearing checked a few months ago. Its OK but...gulp... ...my FR between 7khz and 10khz has dipped, as has my ability to hear higher frequencies over 14khz. Every where else its linear. Doc said its normal for males over 50. \:\(

Maybe its time to change my icon and get one with earmuffs?

Same here, I'll be 50 this year and my Doc told me the same.

I haven't had mine checked, but my wife did last year. While she didn't have significant hearing loss, she does have an unusual sensitivity to loud noise. Unfortunately, this does not pair well with my audio hobby...
