Why do you hear 2 different younds when an A-10 Warthog fires?

707 views

Is it the sound of the powder exploding then the bullet breaking the sound barrier? Is one of them the projectile itself impacting/exploding?

For clarity, I mean it like [this](https://youtu.be/FVQvH4qc5cg?t=22). What is the first, sharper sound, and what is the secind, softer sound?

Haven’t seen the video (YT being difficult), but the first is likely the gun firing, as in the gunpowder exploding propelling the mind boggling number of large Calibre shells.

The second is likely the shells impact sound on target.

That is the sound in this video at least.
