Closest I’ve seen to this being done was the movie Black Hawk Down. Meanwhile can you imagine everyone screaming at each other in the John Wick films? Other movies like Aliens would have been a whole different level of horrifying as the sound fades away until its just the sound of the actor’s muffled heart beat and their cluelessness that the xenomorph is crawling up behind them.
I can do this too, but I still use hearing protection because I’m not sure how well it it actually works at preventing damage
I usually only do it in a pinch but prefer to use protection.
prolonged use of the ability can cause headaches, so I blast it full on just before the loud sound. though, longest I’ve ever activated it was about 5 minutes.
