Can You Hear This? - mrbaggio - 04-25-2007

Make sure you speakers are set to a normal volume before you play the sound.

Play it and post if you can hear it or not.

It is a clip of a high frequency sound that only young people are supposed to be able to hear (below 30). I can hear it at 25. My parents could not at mid 50s. It drove my dog crazy also. Kind of stange for the dog. She is really old and her hearing is failing.

This has been floating around the news for a while, but this is the first time I heard the clip for myself.

My office backs up to a vet clinic. I Turned it up really loud and the dogs went nuts :-).

- BLINGMW - 04-25-2007

Damn. I can't hear it at all. Cry On crappy laptop speakers, but I doubt that matters. It's cranked all the way up!

How old are you if you don't mind me asking?

I played it for my coworkers and the older ones couldn't hear it. At first they did not beieve me that real noise was coming out.

Laptop is ok. That's where I'm playing it too.

29. I'll test it on Jess when I get home, she can hear like TV interference and crap

- Mike - 04-25-2007

there is actually a site that lets you change the frequency... we were messing with it here at work... people ranged from 15k-19k.

- .RJ - 04-25-2007

I am a little deef, and I can hear that...

- BLINGMW - 04-25-2007

hahaha I just sent it to my 23yr old co-worker, he put his headphones on and jumped out of his chair "WHY WOULD YOU DO THAT ME?!" :lol:

I still couldn't hear it Sad

I heard it and my hearing is terrible. Kinda hurt too! I'll be 25 in a few days.

- ViPER1313 - 04-25-2007

Thats only a 15khz tone - most people under 50 should be able to hear that.

A more accurate test of hearing is a sine sweep from 10 to 22khz - you just find the point in the file that you can't hear the sound anymore. You also have to be careful about what type of sound card / headphones / speakers you use for the test. Many sound cards distort the upper frequencies due to re-sampling techniques (ie.. all Creative cards) and bring inaudible frequencies into the audible range. Many speakers also cannot accurately represent such high frequencies.

damn yeah, I can barely hear 13k, my coworkers love me. The 50yr old guy here can't hear 8k lol

I'm kind of sad about it! I've never had a loud stereo, had very little time with walkmans and the like when I was young, and have only been to a handful of loud concerts. :dunno: Now I'm depressed and feeling old, thanks for ruining my day! :lol:

- .RJ - 04-25-2007

Driving to work in a busted ass e30 doesnt already ruin your day? :lol:

- Mike - 04-25-2007

i can hear up to 18.

- HAULN-SS - 04-25-2007

Well, i just tried this - I could hear up to 17k fine, and the only other one I could hear was 21k. It's like I'm deaf to those in between there.

Also - the most painful one to hear was the 9k one.

may try this again at home where I have a good set of speakers
