that sound is not very loud, about like a child's cap pistol.

Thats totaly incorrect. A bullet like this makes a sounds almost as loud as the cartridge going off. Ever compared subsonic to a standard round?

The sound of a supersonic bullet going by is not all that loud. I know this from working targets on USMC ranges.

Perhaps my memory is not all that good, but the sound of a supersonic bullet going by is not very loud.

I wrote some words on this thread about the sound of the shot being fired. After reading more posts on this subject, I think that the volume is very subjective. After firing .44 Mag from a 6" barelled handgun for about an hour, .223 rifle just doesn't seem real loud. But as I said, that first .223 shot at 6:00 AM, in the woods, in November is a real waker-upper!
