in Das Boot and other sub films you often hear the sonar from the boats trying to depth charge them from inside the sub. did this happen or is it something to make films more interesting like cars exploding whenever they crash etc.

the sound you mention is reffered as the "ping" and is as true as can get.
the ships sends a sound wave, and by calculating the time of the bounce of the wave, calculates depth and distance to target.

Hi
I'm pretty sure the later WW2 sonars were not audible,at least to human frequencies.
Anyway I have never operated against a WW2 sonar. However the sonar "ping" heard in almost all modern sub movies is utter nonsense.
Modern High and Medium frequency sonars, I forget the exact figures but these sonars are around 14-34 Khz cannot be heard by humans. Electronic equipment is used to analyse strenghths,amplitude etc. of the signals to work out where they are coming from.
Also they always tend to show a "sonar" display that looks like a radar screen The closest I have seen to a real sonar display was on Hunt for Red October on the American 688.
