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?

In the case of anti-submarine sonar (Mid-frequency sonars). Yes. They use frequencies that the human ear can hear and they’re insanely loud. Highest powered pings are equivalent to the sonar clicks of a blue whale. Even the backwash is loud enough to be audible.
In the case of navigational sonar. No. They tend to operate in high ultrasound frequencies, too high pitched for a human (or fish) to hear.
