SPEED OF SOUND ARMA 3 FREE

There should also be some doppler effect because of aircraft movement, but that's a suggestion for a future thread. The last part, yes, you could hear the same sound again, but the volume would be much lower if audible at all. The server shouldn't have to deal with that information as it would cause even more delay especially with poor latency, but I'm sure there's a way to make the server be involved too if that's necessary. You could also take into account the air temperature and height from sea level, which both affect the speed of sound, but even the basic implementation with a fixed speed of sound value would make a huge difference. Just a subroutine to delay the sound effect playback, because that's what distance does, it delays the sound and drops the level of sound. Yes it is feasible and not even that hard to implement.

Then you would switch back to plane view, and possibly hear the same explosion again. Moreover, when (in example) you follow the fall of a bomb with the bomb camera, you would hear the explosion immediately. Would this require the server to take into account the relative position of every player for every localized sound effect, or would it be the client to calculate the delay after getting the info from the server? This would indeed increase realism, but is it technically feasible? In reality there should be a delay because sound travels really slowly. Total time after shot taken for the hit to take place and the sound to travel back at the shooter: ~2,11 secondsĪs you can hopefully hear from the attached audio clips, the sound is currently instant when the target is hit and destroyed. Time for sound of hit to travel back to shooter: 510m / 343,2 m/s = ~1,49s Time for shell to travel the distance: 510 m / 822 m/s = ~0,62s

Math bits (feel free to correct me if I'm wrong): The speed of sound is approximately 343,2 m/s and it should not be confused with the speed of light which is 299 792 458 m/s.Įxample audio files of firing the 105mm K.18 cannon with Pzgr.rot (822 m/s) at a target from 0.51km distance. This means that the speed of sound is not implemented in a realistic manner and it ruins the immersion if you pay any attention to the sounds.Ĭurrently in the game, the speed of sound is exactly the same as the speed of light.

Be it exploding bombs, someone getting hit by a tank shell or whatever. When something happens 2km away, you instantly hear the sound of it happening as if it happened right next to you, just with a lower volume. Currently in War Thunder all sounds are heard instantly as whatever causes them happens in the game regardless of distance.
