I was just watching a video of two astronauts doing an EVA on ISS to install some things. As I saw how they moved around the outside of the ISS using handrails and other things to grab, I was wondering whether people inside the ISS can actually hear their outside colleagues bumping against the metal or any other sounds that are caused by the astronauts on the outside?
As far as I know, the inside of ISS can be quite noisy so I guess most sounds caused by the spacewalkers are probably drowned by the inside noise. But maybe sounds when using tools (e.g. to tighten or loosen screw s) may be heard inside?
