"Face It... It's Down Hill From Here!"

That was the result from the hearing test at http://www.freemosquitoringtones.org/hearing_test/[^] I'm 37; the highest frequency I could hear was 14kHz. (37,14) Apparently I'm not a teenager anymore! Anyone here young enough to hear 18kHz?
(36,16 (17, using http://audiocheck.net/audiotests_frequencycheckhigh.php[^])) Ah, after considering the frequency response of the entire system, I think it's the crappy speakers in my laptop... Probably roll off enough near 17kHz. If anything, my lower mid range is going. With the above link, I the 17kHz was almost painful. My wife (same age as me) could only start hearing at 14kHz. Using the 48kSps sample, I was able to hear something above 19kHz, however it sounded lower in tone than the 17kHz, so I'm thinking my sound system is down sampling it to 22.5kSps and there are some aliasing issues.

(29,18) at first, and then I saw "Check your hearing, download the Ultra Sonic Ringtones and hear it for yourself!" So I gave those a try. I can hear 22KHz no problem. Is there any higher? (I mean samples of course) I just found a 24 KHz and I could hear that as well : http://www.soundsnap.com/node/36060[^] And after trying out dog whistle smaples: http://www.jetcityorange.com/dog-whistle/[^] I have come to realize that either I have faulty sound equipment or I have a bat's ears. I can hear the sounds being made at 44 KHz but it gives me an instant headache and I actually threw the headphones. Head still hurts after half a minute with an itch behind the eyes.

Not sure about the first link, but the samples at the second link were sampled at 44.1kSps (kilo samples per seconds, as to not be confused with actual frequency content of the data), so anything above 22.05kHz is aliasing. Listening to the 40000Hz tone aliased back to 4000Hz (which is correct by Nyquist theroem, and my hearing), and the 44000kHz tone aliased back to 100Hz, which I couldn't hear, probably due to my crappy laptop speakers having rolled-off on the low end by 100Hz. Even funnier, their claim to play a prank on your dog by using the ultrasonic tones as ring tones on your phone wouldn't work. The speaker on the phone, for the ringer, probably only has an 11kHz bandwidth (hence why nothing has that high fidelity sound coming from it).

that scared the shit out of me. First all I could hear was only the 8khz over the damn laptop speaker. any other frequency, I could not hear any thing. My blood pressure started to climb. I know I am not that deaf, but could not hear any thing except for the 8khz. Then I grabbed my headphone tried it again. That sounds much better, but it is weird, I can't hear the 14khz, but I can clearly hear the 15khz. :confused::~ 15khz @ 36 not bad :sigh:

I think these tests depend on your speakers / headphones as well.

According to the first page my headphones must be 30 and over because they could only do up 16kHz. However, I know I still hear much higher than that (I'm 43), which means I must need a new set of headphones :-D Simple lesson I learned a long time ago. We determine 'loud' by the volume of the lowest frequencies. If you don't want to obliterate your sensitivity to higher frequencies then ensure that you get good bass reproduction. In the case of headphones that means get those that you screw into your skull as they do a really good job of ensuring that external noises are blocked out and that the bass stays locked in. The 'bud' earphones that sit just outside the ear canal are just utterly useless.

Me. Some clever spark decided that it would be a good idea to put a Mosquito device by their house. Every time I walk past on the way to and fro from school, it activates. That's quite an annoyance (borderline painful), especially when there's only one or two people causing the problem
The Caltrain station in San Francisco has a mosquito device constantly running. It drives me frakking insane. Whenever I'm waiting for a train, I have to stand out on the street to get away from that noise.

This file is a much better test. I found the test period to be rather short, so I extend them using Audacity. Don't know if that is cheating. :^) Interesting, I could hear 19K and below except 13K & 14K with either speakers or headset. Either the sound card can't produce those frequencies, I have selective hearing loss or those freq's match my tinnitus!

Same here. I'm 47, and the highest I could hear was 12 KHz :sigh:.

I'm sure at least part of my hearing loss stems from working in a computer center for a couple of years back in the 80's. The fan and line printer noise was incredible. I have tinnitus as a result. --- My daughter's three rodent friends (Chloe, Ivory, and Vala) are members of the review board overseeing Slartibartfast's latest debacle. They just shake their heads in disgust. I'm going to catch a ride with them when they leave. You do have your towel, don't you?

I'm pretty sure I can hear up to at least 20kHz (from a real test with better equipment, they only went up to 20kHz though), but my headphones refuse to emit any sound higher than 17kHz with Audacity I managed to narrow it down to 17,99 - 17,999kHz which I think means that it just drops anything >= 18kHz So anyone who got 17kHz as highest and didn't hear the 18kHz sample.. distrust your equipment!

I'll be 28 in 2 months and could still here 18khz, if only just. (I'll be repeating the test tonight on better speakers, IIRC my headphones have crappy performance that high). Playing around with PC speakers in HS I could hear upto at least 22khz, dunno if that was my personal limit or that of the speaker itself. Everyone else I got to try topped out lower, and I didn't have any sort of hardware to test with.

I definately wasn't hearing anything near 24khz from that...
