Is it the Weight or the Velocity that makes it Quieter?

James Yeager of Tactical Response demonstrates how different projectile weights affect overall sound suppression, and he uses a YHM Phantom. Maybe suppressor owners already know this or not, its worth looking at how the higher grains affect the sound. The higher the grain the quieter it got, simply due to the velocity not the weight. Very interesting video!
