And for more information, women have much better hearing than men.

Indeed we do!

That explains why it's hard to find good male singers who can sing on pitch (i'm very very pitch-picky), while it's much easier to find a female who can do so.

Aflac,

Look it up, the differences in our hearing is profoundly different. Not to mention the difference in the vocal cords/head/sinus.

Is this any way bad for my speakers???

No. Just don't turn up the volume/gain more than you normally would.

 

[imported_Rat]

I can still hear it.

I'm almost 40 and that high pitch drives me nuts. That sound always tips me off if the kids left a tv on in their bedrooms.

The only reason why I hate turning the damn TV on.

3 sounds
1 most pepole can hear
1 the ring tone that mostly teens can hear
1 the tone used to repel the teen loiterers

good find!

No as a matter of fact it's a great way to test (and break in) your tweeter voice coils. After a few short seconds at full output, even the nastiest domes will have that silky sound we all like. Professor Lirpa was exactly right.

2 seconds of that was enough to repel me.

It's fed through an array of piezoelectric drivers attached to a long throat highly directional horn. This is to minimize the effect to people below. Of course it bounces off everything and can be heard anyways. It's funny to watch people walking around tilting their heads, sticking a finger in their ears or even stopping to wonder what they're hearing. :laugh:

You keep pet rats? Try it on them - they'd probably like it. :laugh:

go into audacity,

generate> tone

waveform- sine
frequency- 18000.00
amplitude- 1.00

"

so I could see what frequency affect who ...

BTW. thats how to make the MOSQUITO sound


Thanks a lot!

the mosquito sound is 15khz fyi. big difference from that and 18khz. many speakers can't even reproduce 18khz.

I highly doubt that.

Wow I can hear the first two but not the teenage repel

Note that I am 15.

Well, that's what you get for listening to the rock music, you little ragamuffin.

Or you have bad speakers.

agreed.

laptop speakers, maybe hard to reproduce. Any stereo that isn't a boom box, not hard at all.,

Actually many notebook speakers with their small diaphragms would be ideally suited for producing higher frequencies. Most likely distorted too. A 20KHz tone is good way to find the clipping point - it will be inaudible until the amplitude is increased to the onset of clipping. Back the level down a hair and you're all set. This is good for adjusting at the PREAMP level obviously. A 10kW amplifier running at 20KHz to clipping is probably not a good idea.

I think I've tortured them enough

Maybe I should use it to test the upper frequency response of the Axioms I'm trying out
https://mywebspace.wisc.edu/spmclaughlin/web/Random/Axiom_Angle.JPG

Found some on Craigslist so I picked them up to give to my parents for Christmas. Might as well test them out until then

Try this. :Q

It's a 16KHz burst which is actually a 3rd order subharmonic of the ultrasonic signal used in some cities to count traffic. Those bucket looking things pointing down at cars as they pass below.

Now ladybuggy is getting annoyed. I better stop.

Although... I can think of a great use for this.

At 2am the bar below us lets out and then 5-20 drunken idiots stand around below the door shouting while the workers try to get them to leave. Our two bedroom windows are right above where they end up standing every night.

Some 15kHz+ material might give them some more incentive to move along :laugh:

well you know me babe, the pre-amp is the second most important stage. clip the pre-amp and everything else is garbage.

I don't know, I kinda like these noises... I like the "nails on a blackboard" sound too. I mean, there are other noises I'd rather listen to, but seeing everybody else in the room recoil in horror makes me smile.

Pre-amps? We don't need no stinkin' pre-amps!

Is it possible too like theses sounds, when i posted this (last night) I heard a few and i sent a few so my girlfriend listned to it and we both were like.... F^ck....

Thanks

Alot for the help!!

 

[So]

Having played w/ function generators in lab, I can say that I can still hear well into the 17kHz range, but again, people use pure tones in Rap all the time. Even though I'm not a fan, I don't see how they think they'll repel kids by making 'music'

You're going to need something that sounds a little rougher:

Ouch, gotta get that checked out. It gets all pissy in the morning with all the fog we're having. :Q

 

[AbsolutDealage]

Also, for the OP, you can check out a range of pre-recorded tones Here.
