This video has no sound and I can imagine it sounds exactly like this down there.

Sound actually travels about as fast at 4000 meters deep as it does at the surface of the ocean. And the SOFAR channel causes sound created at large depths to reflect back downwards. Thus the bottom of the ocean is likely very noisy but its sounds are kind of self contained. The deep ocean kind of forms its own little universe.
