Edit following @nedlrichards comment
Jul 13, 2022 at 22:57 comment added nedlrichards I edited my previous answer below due to your helpful comments. I think it is misleading to say "sound generated in air transits easily into water". The same pressure amplitude in air represents significantly less acoustic intensity in water. Overflight of a helicopter is very loud and low frequency compared to many acoustic sources of practical interest.
