This is one of those topics where gun fans will try to take to both sides of the issue. When they are talking to "normies" they talk about how suppressors aren't really that quiet and it's just to protect their hearing at the range. When they are talking amongst themselves they brag about how they were able to get their guns "Hollywood quiet" with subsonic ammunition.
What's most misleading about Hollywood silencers isn't the sound of the gun firing, but the sound of the round striking. In suppressed weapons, the bullet impact is often significantly louder than the weapon firing and should be clearly audible if it's hitting a solid surface.
