This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

At great looking infographic that provides interesting facts about silencers - Devices that suppress the blast created when a gun is discharged.

So a silenced 9mm is slightly louder than THUNDER?

I won't say they are wrong, but that sure doesn't feel right.

Silencers are very badly named honestly. A "silenced" gun is still very loud, it's just moderately quieter than an unsilenced one. People watch movies and TV shows and play videogames that make it seem like a silenced gun barely makes any noise at all and think that's reality. That is very much not reality, it just makes for a more entertaining story.

Are you telling me a silenced gun doesn't make a sneaky zipping sound? It can't be true.

Pew Pew!

Subsonic rounds though! I've seen videos of subsonic 9mm and .22LR where all you heard was the action cycling.

I don't have a suppressor, but I got some subsonic .22LR to play with. Couldn't tell any difference.

I could be full of it.... but I think that's because those rounds are intended to travel below the sonic boom threshold resulting in less noise when using a suppressor.

I always try to go with "suppressed" rather than "silenced".

A unsilenced 9mm out of a handgun is normally around 160db (assuming common ammunition and a common type of handgun). A reduction to 125db with a silencer seems about right.

That graphic is very simple. It doesn’t include important variables like the ammunition type, and the design features or the volume of the silencer.

Absolutely. To add perspective, typical firearm hearing protection reduces sound by 25-35dB.

I'm sure the full story is more complicated when taking into account frequencies, duration of the spike in sound, etc.
