IMHO no-one can prove what can be felt by the body or not, & if it ads or not to recreating the illusion of a live sound, perceived by the brain as more natural.

There have been studies where they rolled off upper frequencies in music and polled listeners to find out 1) if they could tell the frequencies were missing, and 2) if it made a difference to the music. The results were that although listeners could tell if everything above 10kHz was rolled off, but they said it didn't affect sound quality. Above 14kHz, they couldn't tell at all.

The frequency range is not an even scale. It doubles with each octave. So the difference between 20Hz and 40Hz is exactly the same as the difference between 10,000 Hz and 20,000 Hz. When you are talking about the difference between 20kHz and 21.5 kHz, you are talking about a single note's difference on a piano. 15kHz to 20kHz is four notes.

If you are "feeling" a high frequency note by turning up the volume, you aren't necessarily *hearing* that note. Everyone can feel sound pressure from inaudible frequencies if they're loud enough.

The middle of the frequency range is what matters. Don't worry about the stuff only bats can hear.

Care to put a wager on that? I have 20$ and a baseball bat that says you're wrong.

Male 24 and I can't hear anything above 17khz

 

Kind of depressing :(

 

Guess I'm paying for the volumes of my teenage years (not only headphones but target shooting with .308s and playing large guitar amps with no ear protection, etc).

Hmm, in a very strange twist, even though I hear nothing from 17-20, I hear 21 khz extremely clearly. I verified this with the tone generator and slow, massive frequency sweep in my DAW. I mean, I hear 21khz more easily than I hear 15khz.

 

There's just a complete hole from 17k through just below 21 then it comes back for 1000hz clear as a bell, very strange.

 

Moral of the story: shoot with earplugs

25, Male. Can hear up to 22 htz ;). Weird part is I had a harder time hearing 20 htz out of them all. Was the most faint.

I wonder how much hearing damage this thread has caused?

Caused or brought to light?

Caused. Everybody wants to have super sonic hearing and post about it. I'm betting that the higher the frequency, the higher the volume is getting cranked. It's actually kind of irresponsible to encourage people to play test tones on the edge of hearing. It's just too easy, and tempting, to burn 22kHz into your eardrums.

Can't argue there. Would suck if they tried it backwards :P.

After more sine tones and sweeps, I can hear down to 1 hz but only up to 17 khz...

 

New meaning to the term "basshead"?

Am I mistaken when I google lowest audible frequencies and read that most people stop hearing at 20 hz? Wow. I hear practically the same volume from 0 hz through the entire spectrum up to 17 khz

 

I need to get a job on Dune listening for sandworms or something

post #283 of 543

The higher you go up the harder it gets to hear it. The lower it goes the harder on the ears it is lol. Gotta pump the volume down then :P.

Up to 15kHz... It is what it is frown.gif

post #285 of 543

18,male.

can hear up to 24Khz

i didn't really tried this test, but according to my audiologist i can hear sounds up to 24Khz which is really impressive/unbelivable?!confused_face_2.gif
