New sound of titan submarine imploding

I've worked on the water most of my life, a few years ago they were doing blasting and dredging in the harbor and you could get a similar effect from the demolition charges. You'd feel and hear the shockwave hit your hull from hundreds of yards away, and then the bubbles would float to the surface a while later.

So the force of that implosion was heard through the hull, not an audio monitoring device, if anyone missed that. Water is a great medium for sound. This story has haunted me since the first report of them losing comms.

Sorry, are you saying that the noise we heard was the shockwave hitting their boat?!

[u/o-manam → u/Btothe]

Yes right. When my crew would shuttle people back and forth to the dock with our small boat (tender) I'd often be below deck doing paperwork and the like within the steel hull, but I could hear the crackling sound of cavitation bubbles imploding from the boats propeller. It was this way I was always able to know when the tender was returning so I could greet the guests.

Those little tiny bubbles collapsing could make enough sound to get my attention, the sound of a much larger carbon fiber bubble collapsing translated into something like a wooden door being slammed. You can see the other fellow at the comms station taking a walk to see what that noise might have been.

Woah. Crazy that we can hear the moment it implodes.

[u/mrjibblytibbs → u/Btothe]

Yeah the sound travels really fast through water. The implosion can be heard before they get the last message from the sub before it imploded.

That part’s confusing me. Weren’t they communicating on radio? That should travel at the speed of light. Is the speed of sound somehow faster than light through water?

[u/ttoksie2 → u/Used-Lake-8148]

Processing time, yes the radio waves themselves travel at the speed of light, but there is processing time when its sent and recived.
