Default oh my gosh, I can't hear 15kHz :-(

I never tried it before, but there are on-line test sites. I just tried it. I can clearly hear 14kHz, but not 15kHz. Wow, makes my amplifier design and speaker design a lot easier then.

Hearing Test - Can you hear it?

What about you guys ?

Somehow, those tones sound odd! I can hear up to 18 kHz without issues but it doesn't sound like 18 kHz. it sounds much lower. oO

Well the 12Khz was really loud, but I couldn't hear the 14Khz, (my wife could hear up to 16Khz so it isn't the speakers on the laptop). The weird thing is sometimes I could hear the 16khz tone. I think the problem is my tinitis I've got contstant tones in my ears at quite high levels which I think are higher than 12Khz, which are probably masking out the sounds. I probably don't need to worry about the fact my tweeters start rolling off around 12Khz though

I'm pretty sure when I generated tones on the pc and played them through my amp and speakers I could hear up to around 16Khz, so on better quality speakers maybe I can hear a bit more...

About 20 years ago I read a article in stereophile where the author discussed the use of ear plugs while operating loud equipment (routers, lawnmowers etc).
Some people were using cotton plugs. The author recommended against this as people could not get it "all" out when they wanted to, leading to ear infections.
He stated that when he had a nice "listening session" planned, he would wear ear plugs for several hours.
I used to do it ( for a while). Now I just make sure I wear them when my convertible top is down, or I am operating any machinery that is loud.
I don't hear any test tones above 14kHz, am 50 years old.
Maybe it would be worse if I didn't wear the ear plugs.
They're very cheap.

possibly if your using warble tones, you may be picking up the lower end of the "warble" and therefore sometimes hearing whats on the verge of not hearing.

Try opening two separate tabs in your browser, one for each tone so you can play them back to back.

4 out of 4 on pitch test, no problem. I can hear to 18kHz, just about, 22 years. These tests vary so much, the one in the OP I can hear 17K but not 18K as a tone, which is about right.

I always wear ear defenders when using router/jigsaw, I can't imagine not doing so!?
