    Is firing sub sonic ammo through a non suppressed firearm any quieter than firing ammo that is over 1100 fps (roughly)?

    There are two components to the noise a firearm makes (three if you count the noise of the action.)

    1. Muzzle blast
    2. The sonic boom a supersonic bullet makes.

    A suppressor reduces the first, but does nothing about the 2nd.

    If you shoot a subsonic round you don't get the sonic boom.

    It's quieter, but it can be hard to notice without a can. The muzzle blast can drown out the sonic crack for the shooter. It would be more noticeable for people farther from the gun.
