[Phys-L] Re: sound travelling through a solid



Brian!

I don't think wave guiding was what meant. I'd compare an air filled
tube with a solid tube. The question (the miss match between air and
the tube being the same as the solid and air, tho reversed) is which is
least elastic.

"After traversing a path of reduced attenuation, I suppose that
the sound would indeed be louder than otherwise."

yes, which attenuates more?

bc

anyone point me to some more information about this (preferably on the

I believe that one could find evidence for the reduced attenuation of
sound transmitted through solids cf air. A distant train
telegraphing its approach through the rail is reminiscent of a wave
guide for em waves, to my mind.

After traversing a path of reduced attenuation, I suppose that
the sound would indeed be louder than otherwise.
