Last month we were doing dives at Netrani (15-20 m depth) and on each dive i was hearing this haunting sound "wooaaaanawoa" at very high pitch, which would last for about 15 secs and stop. I was trying to locate the sound but could not and on four dives the same thing happened to me. I asked my buddy and he also heard the same sound . There are migratory whales around these parts and I though maybe it was one of them. When I asked few very senior divers about it they said its my tank o-ring leaking and at certain positions the leak increases and makes this noise. Pretty weird.
