Active sonar Pinging in the hunt for the Red October and DW

[Castout]

The difference between the pinging in the movie and DW or SC is so wide.

In DW you hear a high pitch sound while in the Hunt for the Red October you get a bouncing sound of a small stone being thrown off the hull.

Which one is more realistic. The hunt for the Red October imo is a very realistic movie well apart for the hydrodynamic propulsion system .

I would like to mod the pinging sound to sound more like the hunt for the red october but I have my doubts since I have no knowledge whatsoever on how an active pinging sound like in RL.

Any clue? I'll share the sound which I took from SH3 mod if you want it or provide you with the link.

I mean the name is active PINGING and not active HISSING.

I remember a thread back then when everyone seemed not to like the default SC pinging sound effect.

Anyone can tell me which one is more realistic?
