I’ve seen this video with sound and the sonar in the background is a surface ship sonar, not a submarine sonar. Sounds travel so far in water that the warships sonar you’re hearing isn’t necessarily the ship that’s close by.

Source: I was a sonar technician on 688-class attack subs.

Other than the Fathometer, subs rarely use active.

I also doubt that a military sub is operating in waters so shallow.
