Speed of Sound = delay of sound with distance

[Dutchmill64]

My humble thoughts:

 

I notice in a lot of video captures that the sound of an explotion takes place at the same instance that the explotion can be seen. But in my opinion the sound of e.g. a plane exploding should be relative to the distance to the camera. 12 m/s Sound of speed at 20C So the farther away it happens, the more of a delay of the sound. It would be more realistic in that way. Just like the delay in sound when a plane passes with Mach 1 and has a delay in sound.

I have noticed a delay in sound when watching explosions from distance.

There's definitely a delay based on distance and speed of sound when you watch explosions in DCS. I have no idea if air density is in the equation anywhere, but I'd say it's a pretty good approximation of how it should work.

 

IMHO

The fact that you have seen videos that don't behave like that might be due to editing or simply to the fact that the distance from the camera was not sufficient to make a significant delay happen.

Growling Sidewinder edits the explosion sounds on his videos when a missile hits, so thats where you probably got that from. In the sim itself speed of sound is a factor and with distance the delay will increase.
