Damn, I only got down to the fourth one at 14.1kHz and I'm only 41. But my wife could have saved me the trouble.

Everything is going (hearing, memory, and nearsight).

BTW, the highest wave that can be produced with the 44.1kHz sample rate used is 22.05kHz, and that would be as a square wave, not a sine wave.

So even if the 22.4kHz sample wasn't silent, it still wouldn't really be a 22.4kHz tone with that sample rate.

Lots of distortion on the other high frequencies below 22 as well because you'd really need a much higher sample rate (more than most computer audio is capable of) to do it right.

The whole concept of using these as phone ringtones is also BS. Most phones play mp3 ringtones with a 16kHz sample rate (the 44.1 kHz samples there would get downsampled if they played at all), so the highest tone your phone can possibly produce is 8kHz.

For those saying the last file is empty, it's not. It's actually filled with zeroes. It's mute and there's still data there but it's very simple. Mute files can be used to determine the noise floor of your playback system.

So even if you choose not to decide you have still made a choice. - Rush.

They should make a shocker phone!

They have these collars for training dogs to stop barking. They have probes connected to a very efficient inverter that can produce high voltage pulses >6kV.

Why not retractable ones on the phone so when it rings it shocks the user? Unlike vibrate it would be totally inaudible. (but most people would twitch hehe) Hacking would actually become fun again as the next Kevin Mitnick would have a way to surreptitiously crank the shocker to the max and watch in hysterics as the person called walks funny or screams! :laugh:

EDIT:

Here's a 60 second long log sweep covering 1 Hz to 22,000 Hz. It was recorded at -3dB to allow for headroom.

I start hearing at 17 seconds and stop at 58

That's pretty good. Before 15 seconds or so is more of a speaker test than anything else. :Q

Isn't it true though that the hearing range for a human is 20Hz to 20,000Hz? So even if the final clip played, you wouldn't be able to hear it anyway.

Edit: Found the wiki site confirming this.

You need to give a warning to lower volume first on this one LOL, it's MUCH LOUDER than the "ringtone" link.

There is some kind of high frequency beating noise in the sample. The continous low pitch tone is much quieter than the sample until 15s in (after that the noise fades into the background relative to the increasing pitch tone).

The first 15s have some kind of high frequency beating noise before it gets to the continuous tone. from 20s or so until almost the very end is loud (putting the beating high frquency noise in the background) The continuous tone gets much quieter in the last 1.5s, where you can hear the beating noise again.

The tone is pure sine wave with no noise at all. If that's not what you're hearing there is a fault with your playback system or your ears. (highly unlikely on the latter but everyone's perception differs! )

that may be my problem I could only hear up to 18.8kHz and I'm 16...

17.7 for me.

Age = 29.


Edit: Oh yeah, that's in a NOC full of servers and rack equipment all with fans plus a loud ass AC. And I'm also an active musician in a rock band too!

I can hear up to 21.1kHz. I can only hear it if I turn my head sideways so it is going straight into my ear. I can't hear anything if I just look straight at my speaker. I can't hear anything out of my Sennheiser HD580 headphones.

One interesting thing is my speakers are only rated up to 20kHz +-3dB, so I'm willing to bet my speakers aren't doing a very good job of playing that sound. There's no way a cellphone is going to cut it.

Wow, that's kind've depressing.

I can't hear 12kHz.

I can hear 10kHz pretty well tho.

At normal volume, 16.7kHz is very faint for me. Sounds about the same as that irritating tube television pitch.

At high volume, I picked out all of them, but I doubt the sound files are very good quality to make any judgments.

TV hsync frequency is 15.734kHz. Pretty close

Hmmm.. I can hear them all with headphones.

The high frequency drivers in my speakers must suck.

You are a liar
You claimed to be able to hear a tone that contained absolutely no sound!

The highest pitched ultrasonic mosquito ringtone that I can hear is 22.4kHz
Find out which ringtones you can hear!

I can go t o21.1 but not sure if my speakers can even do 22.4 so eh...

wait...
Hearing test results

maybe 22.4 dosent exist.
