Say you are shooting a pulse at a ship, will someone in the target ship hear said pulse? If they were leaning on some part of the inner hull attached to the outter hull.
Second question, does the using the sonar hear their own pulse? Like some joe in the mess hall is having having coffee and the technician decides to ping somewhere, if its quiet enuff will he hear it?

Not really. Firstly noone listen to sonar anymore. Moder sonars give visual output for human operator but long long time ago there were accualy people who have been interpreting signals as they went but it wasn’t nearly as precise nor as useful as of today. Secondly sonars don’t use frequencies humans can hear. That famous beeping sound is just an indication that sonar is working, and before computers that signal was shifted if frequency so operator would be able to hear it.
