Mosquito Tone

17KHz I can hear and feel in my skull.
18KHz I can barely hear.

Thats neat though, I've never seen a site where you could play the tones simultaneously.

Edit: That was with the Santa Cruz equalizer off, I tried it with the equalizer on and maxed out the 15KHz bar. Now I can hear them all but the tones are all off, some are higher than others. I guess that's a sampled filter / amplifier at work.
 
This of course assumes your speakers can properly reproduce those frequencies.

That said, 18kHz does play something extremely high-pitched, and audible, on my Logitech Z-640s.
Age 26.

I couldn't clearly hear 18, but I could tell the difference when the tone was playing/not playing. I dunno if that makes sense.

I heard the rest of them clearly enough. I am 33 and I've damaged my ears pretty badly over the years. I couldn't imagine how bad other people's ears must be if they can't hear those tones.
 
Interesting. I was disqualified from pilot pursuant status after failing the hearing test 3 times. They said I was tone deaf in the upper frenquencies. They never said which range, but now I know. I can't hear anything 16khz and under.
 
I can't hear 18.

I'm 38 years old and I get frequent hearing tests in the military. We use a sound-proof booth and head phones for our tests, so using the speakers at work isn't a good replication.

Despite shooting weapons and being around aircraft and vehicles, my hearing is acceptable. Hearing loss is cumulative, so I still bring my hearing protection in case I need to use it. Ear plugs are cheap.

I hated that booth. It was too damn quiet. I started imagining sounds because I was expecting them. HAHA

Same with me. I can tell "something" is going on at 18. 17 blasts my skull out. I'm 29.

I can hear them all well... but for some reason 16 is different than the others. Is it just me?

EDIT: 22.

I showed this to my father and his reaction was really strange! He said he could hear most of them but that the higher pitched ones actually sounded low pitched to him. And he couldn't hear the 13khz one at all.

Hmm. 16khz fades in and out to me, unlike the others. Maybe it's my headphones.
 
i could hear 14 barely but not 15 im 42 and have worked around loud equipment most of my life.

edit: okay if i crank the volume i can hear up to 17. if you go too loud i think 16 will make a buzzing.
 
30 years old. I can hear them all, although only barely 17k. 18k is more audible than 17k, oddly enough. Maybe my headphones are doing it wrong.
 
can hear up to 17 khz. 17 khz is still very loud but 18 khz I just hear a buzzing.

Anyway I think this is very equipment dependent. 17 kHz on my laptop speakers sounds almost inaudible, but my senheisser headphones play it very clearly. I'm not too convinced that the onboard audio out can reproduce the high frequencies properly.
 
I can hear up to 17, at 18 the only noise I hear is the sound of the start/stop button. Well I can hear 18 if I turn the volume up some, but that's not what I normally listen at, so I won't count it.

Uggh god, play them all simultaneously, really annoying.
 
I'm confused. I'm 19 and haven't had any difficulty with hearing or any damage done to my ears, but I can barely barely hear anything over 15. Sad day 🙁

That's very possible. Might explain why I can hear 17k/18k, but not 16k. Soundchip might be giving the wrong signal to higher freq?

Erm... You mean you can't hear anything over 15kHz?

Normal human speech is in the range of 2-5 kHz (which presumably you can hear).

Wiki has some other frequencies to test yourself on -

http://en.wikipedia.org/wiki/Audio_frequency

The 16.7kHz frequency is "easier" to hear than the 17kHz mosquito I think....


I can make out all the way up to 18kHz on the mosquito test - 27 years old.
