It's a closed system, it does not matter where it is.

from www.dictionary.com :
"–noun Thermodynamics.
a region that is isolated from its surroundings by a boundary that admits no transfer of matter or energy across it."

Why would it matter?
And why would the inside behave differently when in a vacuum?

Yes, it just would be pointless as both the person using the stethoscope and the person being examined would not survive..
but seriously. The transfer of energy into the stethoscope does not require a surrounding medium. One could hook up a motor to the probes membrane and actuate it that way.
It would still be able to transfer low frequencies to the ears.
But if you see otherwise then please explain why a stethoscope would not work in a vacuum.
Even better, explain why a stethoscope would be unable to transfer frequencies lower than 2x its lenth. |

It would transfer them, the particles would just vibrate about their equilibrium and set up a wave of compression and rarefaction............to hear the pitch of a low frequency sound wave, half its wavelength will need to be able to fit into the space......now if that space contained a wall which was not solid enough to contain the wave then yes you would hear the wave.

Well, that's a good description of a sound wave propagating, isnt it?

why?
and why are you mixing psychoacoustics with physics?

lol......it really doesn't matter what happens in the physical world if we are no there to experience it..........sorry but psychoacoustics are very much relevant for as long as there is a participant in the equation......which I think you will find there is

nice try...
It's just that our hearing as a psychoacoustical system has nothing to do with half wavelength anything. As long as a pressure change occurs at our ear drums (relative to the inner ear pressure) we can hear things (of course withing the hearable frequency range, but this is not the discussion).
but, if you like, please explain how the mechanics work for not hearing freqs below 2x stethoscope lenght (which will be anything below about 300Hz or so for a meter long stethoscope).

look I don't use a stethoscope.......just not my area, at all.
you have an obsession with it........if it really is important to the topic then YOU explain.......you brought it into the the thread.

You may know nothing about stethoscopes but you'd have to agree that it is a case which should exhibit your half lambda phenomenon, wouldnt you?
You've been arguing for a few pages against me that it should and now suddenly you dont know anything about it?
Come on now, dont be a spoil.
Enlighten us...
