Mine is from 40Hz to 14 kHz

70 to 14 here

OK, I'm kinda amazed that wasn't some shock vid.

Just before 30Hz->14KHz here.

Of course, do note there'll be differences based on people's speakers etc. Some speakers/headphones can't reproduces certain frequencies, so this is as much a test of them as of your ears.

20Hz to 14kHz. Although, at least for me, the audio appears to completely cut out at approximately 10.8kHz to 11.3kHz, then continues to around 14kHz where it abruptly drops out from then on. Tested on Sennheiser HD650's with a frequency response of 10Hz - 39kHz.

There are some definite volume things with my speakers.. at certain frequencies the damn near blow my ears off and others are very silent. My speakers only start making a sound at 30 something hz, but the floor is shaking from it.

I had the same range as the above posters with the same dropout at 10k.

30 hz to 13 khz.

40 hz to 13 khz. Drops out between 10-11 khz here as well.

20hz - 16khz - I'm not deaf yey.

200hz to 10khz, i didn't use headphones though, just my asus eee onboard speakers. I'm not surprised, honestly. Years of playing loud music and running chainsaws without earplugs, i pretty much asked for it.

I'm pretty sure the high ends don't work well, if at all in this test. The sounds seem to break around 14k, I can hear slight beebs at every k after that, but I'm sure that they're not nearly as high frequency as they should be, and the sound isn't continuous at all, just very short beeps on each k.

I doubt it's your ears, it's your speakers treat. Try http://www.phys.unsw.edu.au/jw/hearing.html with some proper headphones.

30 Hz - 14 kHg

I find this test both existential and frighting.

Does anyone NOT lose sound for a moment between 10 and 11?

I don't think volume makes any difference here. If you can't hear a particular frequency, you shouldn't be able to hear at any volume. Volume doesn't change anything for me, except for a bit of speaker rattle in the low end.

I need to test my cats now.

Try playing two or more of these at different time intervals. Put a few close together and notice the interesting pulsing in the low register. Try to tune them to intervals if you have aural skills. Open a whole shit load and drop some acid. This is a fascinating tool.

I'd love to see a large discussion on this. Free *promotes for those who come up with creative things to do with this interesting tool.

I just tested mine using a crappy pair of Sony earbuds, and I got the same response as Majortomyorke. This makes me a bit suspect of the test. At 20Hz it's pretty much an ear shaking bass, and I don't think there isn't a way anyone couldn't hear it or at least feel it if you had earbuds in with the volume turned up. Plus, the audio was going in and out in the higher freqs.

at about 40 this is positively house shaking through my Klipsch..

I have exact same results as majortoker

your what?! i thought you were a dude!

ahem

umm, pretty much same results as everyone else.
on crappy headphones.

Sound is pulsing vibrations per second, and you can very clearly hear this by opening this vid in two windows and delaying the 2nd vid by a second. The two pitches will clash resulting in a pulsing overtone. The overtone should be high enough for you to be able to hear much earlier than you hear the fundamental, and will pulse from 1 vibration per second up to thousands per second. (If you have a tuning fork at home, it likely says A=440 which means 440 vibrations per second, which is an A in the western tuning system)

This would be a nice way to teach the physics of sound. *science

20-13k, but i was at a club last night.

20 actually sounds like a car very far down my road approaching my house. No big surprise there, just sayin!

25ish Hz to 14 kHz here. It's scary though because for me I notice certain freqs dropping in and out really quick depending on the ear.

Here's a really interesting set of audio tests:http://tonometric.com/rhythmdeaf/

I've taken my upper-end at work before, in a sound proof room, and could follow with good detection accuracy up to 17.4 kHz (labmates typically maxed around 16.8... I win).

The lower end is highly dependent on the speaker, and tactile detection of vibration at very low frequencies can be confused for hearing. The upper end is also speaker and background dependent. If anything I thought this ramp test might show people where they have 'notches' in hearing: frequency ranges where they have hearing damage in one or both ears. BUT, with this poorly compressed recording on my cheap Monsoon pc speakers there were all sorts of fades and rises in amplitude.

I wouldn't use this to test hearing, or even test speakers, but it was fun rumbling around on the low end.

I might be offended if it weren't true.

30 hz to 13 khz.
