Is it that these sounds cannot be faithfully reproduced or that people don't want them faithfully reproduced?
For the gunshot example specifically, my intuition is that it should be possible to fool someone into thinking a gun was fired if the signal chain from capture to speaker is designed with this goal in mind.
Basically the opposite of a movie where viewers want to be able to comfortably hear dialogue and gunshots.
- londons_explore 3y agoI believe they cannot be. Gunpowder has about 3000 joules of energy per gram. A shotgun cartridge might be 30 grams. A decent chunk of that energy ends up as the audible shockwave. That shockwave comes out of the muzzle in about 1 millisecond. Therefore, a speaker system would be needing an instantaneous output power of 90 megawatts to replicate it. 90 megawatts is a small powerstation if you wanted that much energy continuously. Typical large home speaker systems might go up to say 100 watts - or 900,000 times less power than needed. (this analysis glosses over lots of details, but I believe the conclusion to remain the same even if you take those details into account).
- peepee1982 3y agoYeah, but the sound energy usually dissipates by the point it arrives at your ear. Unless you shoot a gun right next to your head, which is probably not what you want to replicate.

- peepee1982 3y agoThey could be reproduced, but it would be expensive and impractical for most environments. Actually I think recording the sounds with a good dynamic range is probably the harder problem, but I'm pretty sure with some post production that would be possible as well.
