Suppressed subsonic 300 blackout is pretty darn close to the movies: https://www.youtube.com/watch?v=1AUDVoGOCxw https://www.youtube.com/watch?v=1AUDVoGOCxw

  It's quiet enough that those guys are not completely crazy for not having ear protection — but of course the microphone is not picking up the full volume of the shots either, any more than it does for unsuppressed, supersonic rounds.

    Microphones generally are very bad at picking real volume of gunshots, silenced or not, subsonic or not, small, large and massive calibers alike

  Not when you're standing right next to it with no ear protection. The peak is still going to be on the order of 115-125 dB at the muzzle even with the best can. This is well within hearing-safe territory (<140 dB per OHSA). But that is still louder than an auto horn! As others have noted, recording equipment doesn't register these levels reliably, so watching a recording does not reflect the actual experience.

    Uh… the highest limit osha has on sound levels is 115db. 140 is a jet engine. A chainsaw is 110

      That's for continuous noise like engines. OTOH "exposure to impulsive or impact noise should not exceed 140 dB peak sound pressure level".
