Solids can propagate sound but you need fairly specific conditions for that sound to be picked up. For example the Apollo video picks up the sound because the astronaut is hitting a metallic object against another metallic object and this creates a very intense sound that transmits well.

" It is true, however, that sound cannot travel in a vacuum so you do not hear things outside. When you drive a bolt or tap a piece of equipment with a tool, you don't hear a thing. "
Metal on metal,
"you don't hear a thing"

we also know NASA classes the "atmosphere" densities of the lunar surface and that surrounding the ISS as comparable, in effect a vacuum.
Has this phenomena of sound travelling through spacemens arms when hitting metal on metal ever being recorded on the high quality audio from an ISS excursion ?
Or has any spaceman reported this phenomena ever during an ISS excursion ?
Also we have instances with sound transmission without contact,
quite the conundrum I'm sure you will agree.
