Ringtone adults can't hear...

[RockMonkey]

oops!

I'm still messing with tones... I'm having fun with this.

Here's a 5Khz to 17Khz in 10 seconds

You don't want to hear some of the modulated tones I did... those will drive you nuts.

Don't wake up your baby turning it up to see if you can hear it.

 

[Hickey]

Oof! heard that... It only faded out at the last second for me.

 

[Herzog]

Remind me to Roshambo when I see you I can hear those as well or better than the one in the article

send me the highest one you can make

I can make them as high as you want.

Here's a 20Khz. If you can hear that, you are freaking crazy. I don't even know if certain speakers will transmit that tone.

Call me a bat. What are you listening to it in? Everything I've tried it's not hard to hear at all.

Not many people notice tones above 20Khz!

I'll have to try later with a good set of headphones. My current speakers may not be up to par. Metal dome speakers will transmit 20Hhz sounds better than plastic. FYI.

Here's 25KHz

It's a larger download because I used a larger sample rate.

I put them all on my cell phone (had to convert yous to mp3) and put it on speaker phone.... I can hear them with out issue.

 

[bobmed]

I can here it barely if I turn the volume up all the way.
my neighbor heard it from her driveway.
I was told when I got out of the navy not to
waste my money on a good stereo.:-\

You're messing with me right? If anything they are getting easier to hear

I can hear this fine in winamp but mediaplayer classic tells me no codec, and I try to convert it in Creative wave studio and the program closes when I click on save as

 

[bobmed]

I could here the 25khz ok

Sounded weird, but I can hear that easier than the one from the article

 

[Brett]

Guess I am good on hearing. All of those I can hear without a problem.

I found that there was fuzz on the WAV files that you made for us. I could hear the fuzz but I am pretty certain it is impossible to hear the 25KHz sound. Also being as the frequency response even for good speakers is only 22Khz... I think that may answer the question. Your speakers may be trying to generate the sounds... but you might just be hearing the attempt. does that make sense?

 

[Herzog]

Ahh, I tried the 25KHz with different speakers and the volume cranked. What's happening is you are hearing a resonation of the 25HKz, but not the true tone...

Exactly. Except there is no fuzz in the actual WAV file... It's a pure tone. What you hear is your speakers clipping. You have to turn the volume down to what you normally listen to and then play the file.

That is pretty cool. I can hear a hum type sound in my speakers when I play it, but in the windows media player I can "see' that the tone is changing, but I don't hear any of that. Even when I crank the sound up. I figured that maybe the hum was what I was supposed to be hearing. So this morning I played it around my 4 year old and he says "what is that phone sound, where is that sound coming from" He is defiantly hearing things that I don't hear.

I used the SA at work to generate a 2khz sound(it has a super speaker) I couldn't hear it until it came down to 18800hz, it was kind of wierd, I could see it on the scope, but I couldn't hear a thing. I cranked it up to 23000 before my 7 yr old couldn't hear it.

I've got my comp volume on 100% winamp on 5% and my amp on 2 (of 8) and the only one that hums is Herzog's 20Khz file the rest including the 25Khz file are a high pitch wtf am I listening to this **** sound.

But then again in school I used to walk to the other end of a hall way to turn off a TV or computer monitor that someone left on... and my hearing is actually better now than it was then (I have ear plugs in a LOT)

 

[Brad]

I can hear it, which is surprising since I trashed my right eardrum a couple of years ago. Can hear it just fine, my hearing must be coming back.

 

[bobmed]

that explains it
I can here a hum but no high pitch.
