Ping....... Ping..PingPingPingPing

[BulSoldier]

Well another question then . DId the submarine crews had any other way to find out that they are being pinged apart from hearing the ping ?
If there are no other ways i find it rather strange why not all asdic equiped ships dont use freqencies that couldnt be heard.

well but in this case.. ASDIC operator wouldn't hear it too

They couldn't hear the real ping.
As the war progressed frequencies got higher and where far beyond
human hearing.

ASDIC sets primary used visual displays to inform the operator of the
results. First needles, then CRT displays. Any audio feedback for the
operator would need a reduction in frequency several fold.

In a sub you would not hear 1940s ASDIC unless it was from very near the
sub and aimed directly at the sub. Even then, the sounds produced are
secondary sounds and not the sounds of the ping it's self.

Hmm, it seems that UberTorpedo no longer has a link to realistic ping sounds.

As someone else said in that thread, after reading all this, I think i'll just cringe every time I hear the Hollywood ping. This has to be one of the most interesting aspects of submarine warfare. Surely a helpful modder with a simple audio program such as Audacity can knock something together for us? I'd have a go if I knew what the hell I was doing!

Those sounds aren't from a WW2 escort, those are modern day submarine sounds...like a 688i, Seawolf...etc....those are definitely not from a ww2 escort.


TarJak has the correct sounds....the ones from the uboat site would be from modern day subs and in all honesty most of them sound like he made them himself...

Of course the obvious answer is the rain of depth charges exploding around them. I'd say that would have been a clue.

But seriously, no way they could have known unless they heard something. Maybe if the hydrophone operator had his equipment tuned to listen to the same frequency as the ping he may have heard it, but TBH I don't even know if that was possible.

Maybe this is something the Mythbusters could do a spot on?
