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

[Bigun]

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 ?

 

[EBM_dude]

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

 

[aptquark]

Considering what the other tones sound like...I cant hear 15 either...AND DON'T WANT TO!

 

[Bigun]

This one is pretty neat, I score 4 out of 4 this time, so I feel better...

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.

...wtf was the answer to 3? no difference?

 

[pforeman]

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.

 

[Bigun]

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!?

 

[EBM_dude]

Whenever I'm around where it's loud like discotheques, power tools, etc. I wear ear protection. I like to listen to music, but that makes it necessary to actually hear the music...

I've thought about that before. When I use the router I ALWAYS use ear protection. Sometimes I'll be working the router for a solid hour or two. Then when I pull off the noise canceling head set (type you use while shooting guns) it's like a whole new world of sound.

You are asking the wrong question IMHO.

The question should be, could you hear the difference between a square, triangular and sine wave at 5kHz.

Music is not pure sine wave, unless you listen to sine wave as music.

[EBM_dude]

This is interesting. I never considered different wave forms in hearing tests.

 

[EUVL]

15kHz is 3rd harmonics, 20kHz is 4th harmonics for a 5kHz fundamental.

There are enough publications to suggest that the human ear is much more sensitive to high order harmonics.
So the fact that you cannot hear 15kHz sine does not necessarily mean that you don't want them present in your music.

Back in high school electronics class someone hooked up a tweeter to a signal generator and maybe 90% of the class could not hear 18kHz even at several watts. Some even stuffed their ear into it. I think the output was measured reasonably flat to 20.

I made it to 18 but was seriously surprised no one could hear beyond that out of about 20 people about 17 years old. Maybe the upper 2 kHz is mainly only for female children?

Anyway I'm limited to about 17 kHz now and at normal listening levels it's mainly inaudible. No wonder older folks get into "full-range" speakers.

 

[Bigun]

My kids just tried it - they had no issue up to 18kHz where the web site test ends; they're 10 years old max.

I look on the bright side, I won't by buying any expensive super tweeters for my full range projects and my tube amps can use the more economical transformers.

I can hear all of those up to 18k on my internal laptop speaker (speaker singular lol). So I think I can hear fairly high.
