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?
