Need audio tranducer to 50 khz

[amdx]

I'm looking for a transducer and preamp to record audio up to 50khz.
Seen any circuits or transducers for this bandwidth?

** You have made two mistakes already.

The term "audio" refers to an * electronic signal* with band limits the
same as the ( human) audible frequency range - ie 20Hz to 22 kHz.

So - do you want to detect and record only supersonic sounds OR do you
want to be a total wanker and extend the audio band to supersonic
frequencies for audiophool reasons ??

That's very nice, ordered two, oh wait $1,954.00 each. Cancel that order!
Looking for something 2 to 3 orders of magnitude less.

Neither, I want to record vibrations of air molecules up to 50khz.
Thanks for the clarification, all without name calling. Well, "wanker"
but that doesn't even register when coming from you.

Tssk @ you Phil.

That's "ultrasonic". Made the same mistake myself before of course.

Maybe he wants to record bats ?

Any idea what the panasonic electrets mics are like above 20K?
e.g.

The piezo tweeter horns come in about 2K and up go to about 40khz

** Just as ambiguous and meaningless as your last post - wanker.

Kindly state the LOWER limit of your frequency range.

Then state the lowest SPL you need to resolve - cos resolving random
molecular motion is a very big ask.

ISTR that WES had a variety of "ultratweeters" with responses even
above 100KHz, with response data to back it up. Check in their PDF
catalog: http://www.wagner.net.au/

Are you saying you want to record the thermal noise of the air?
If so, how do you expect to differentiate from the thermal noise of
everything else, the diaphragm, case, backplate input resistance, amplifier
noise, etc., etc.?

Some clarification of the total frequency range, bottom to top, plus the
displacement, velocity or SPL level expected would be of help. If it is
sound waves you are trying to measure, what is their source?

 

[neon]

you got him straight yet 50 kc i am not sure that i can hear 10 kc language for most people is limited to 5 kc like AM band. some guitars amps go up to 100 kc because they modulate to get histeric sick about it.

 

[amdx]

Are you saying you want to record the thermal noise of the air?

No, just getting info to record sound from 20 hz to 50 khz, the source
of sound would be a muzzle blast. This seems to be an inexpensive solution
get the frequency response.

** God, you are so dumb.

Where does it say that electret capsule is flat to 50kHz ?

Where does it say it can handle the huge SPLs of a gun shot ?

BTW What is this "muzzle blast" ?

From a BB gun ?

A .44 magnum ?

An 8 inch Howitzer ?

At what distance??

ROTFL !!!

What a fucking, know nothing WANKER !!

I don't see that the article says it is flat to 50khz it also doesn't say
it isn't flat to 50 khz.
The original info I received said the modified WM-60AY had a frequency
response from 20 hz to 66 khz, but it didn't say +/- 3db, +/- 10db or +/-
30db so it does lack some detail.

Where does it say it can handle the huge SPLs of a gun shot ?

The article doesn't say anything about SPL's of gun shot. It says the
modified WM-60AY can swing 5vpp max at 141db SPL. I don't know if that is
enough, but I suspect the distance can be adjusted to reduce the SPL.
Can you add anything that will help the project?

BTW What is this "muzzle blast" ?

Something between a .22 and a .44.

What a fucking, know nothing WANKER !!

Why this need to degrade and name call that comes through in almost all of
your posts? Does it make you feel good about yourself? That is a poor
substitute for real self esteem. I do want to compliment you, I have seen a
decrease in the worst of your tyrades. Keep up the self contemplation, I
know it's hard work, but your doing better everyday.

I don't see that the article says it is flat to 50khz it also doesn't say
it isn't flat to 50 khz.

So you assume it is flat? Good move.

The original info I received said the modified WM-60AY had a frequency
response from 20 hz to 66 khz, but it didn't say +/- 3db, +/- 10db or +/-
30db so it does lack some detail.

So it's useless.

your posts?

Cuz he's Patrick. Reason enough.

** Bet you think the earth is flat cos it don't look bent .....

ROTFLMAO !!!

The original info I received ...

** Please tell us, cos we would all dearly like to know.....

What frequency are the Martians transmitting to you on ???

AM or FM ??????????

The article doesn't say anything about SPL's of gun shot.

** QED.

It says the modified WM-60AY can swing 5vpp max at 141db SPL. I don't know
if that is enough, but I suspect the distance can be adjusted to reduce
the SPL.

** Go away from the source and there are no supersonic frequencies left.

Can you add anything that will help the project?

** Gotta know what the **** you are trying to do first -

you ASININE CUNTHEAD !!

Something between a .22 and a .44.

** No precise answer possible ??

Thought so.

Why this need to degrade and name call that comes through in almost all
of your posts?

** Why the need to post ASININE BULLSHIT TROLLS ???

Say what YOU fucking want to do and why !!!!!!!!!!!!!!!!!!!!!!

Or else - GO DROP DEAD !!!

YOU MISERABLE KIDDIE FUCKING **** .
