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.
