Can you hear this?

[moribundman]

There is only one brave enough to take on this challenge?

I heard this last year on NPR and had to try it in my office. A 24 year old co-worker begged me to sto while a 30 something could only hear it out of one ear! I was (and presumably still am) totally deaf to this sound.

Sounds like a CRT to me as well (as CivicFan stated). Hmm, I wonder if I play this sound loud enough I can convince my boss I need a flat panel LCD monitor. I've got a Sony multiscan G520 that was really good in its day but it is starting to get a little blurry. My boss just tells me to not run the resolution so high. Augh.

I can hear the cell phone ring. Gives me a headache and makes my ears ring really loud. So now with my ears ringing - I can't hear the old geezer thing all that well but I can feel the headache while it is playing - and when I hit stop the headache goes away.

I'll have to play these files on my surround sound at home. My little laptop speakers/headphones just can't play it well enough.

 

[CivicFan]

Audacity says that the geezer test has noo sound in it. It's a flat line at 0 dB.

Nice joke though.

 

[moribundman]

There's always a geek who has to be a spoilsport, CivicFan.

aha... aha... @ geezer test .

Now that you mention it, the cell phone ring is around the same pitch as my tinnitus, but a little higher. 24/7 gets a tad annoying.

On the 2nd "Geezer Test"- can't hear anything at all. Not even on the Koss 'phones. Is there a tone at all, or is it a "sound of silence" as someone posted above?

 

[Chris142]

If I turn the puter all the way up and put my ear to the speeker I can barely and I mean barely hear #2.

 

[moribundman]

You got really good ears, Chris!

 

[Chris142]

Is there a sound there or is it just my puter noise?

 

[Chris142]

I think I'm hearing my puter noise

I didn't hear a thing on mori's but didn't want to admit that I'm deaf as a post.

 

[ikeepmychevytoo]

aargh... why did I cranked it up. Guess I'm a teenager... well thirteenager...

Nice toy. Studied ergonomics so I know I won't hear a thing at some time while T is approaching infinitum. On the high pitch side average threshold stimuli loss is about 4 KHz, which is quite a room for toy making.

#2 is complete silence, as Civic pointed out. mori just wanted some of you to become paranoid.

#1 is a 15 kHz tone. When we're young, we can generally hear up to 20 kHz. As we age, the frequency range we can hear narrows. Many elderly won't hear much past 8 kHz.

BTW, this is the freq. spectrum of #1:

Of course the quality of your speakers matters too. #@$%! speakers may be limiting your computer's reproduction of high freq. sounds.

I stopped using the audible tone for continuity on my Fluke DVOM, because its the same as my tinitus.

I heard it loud and clear. I hear noises like that all the time that my friends think I'm crazy, I can even seperate out specific noises in machinery. then there are the voices that nobody else claims to hear...
