I have witnessed them being fired, they are a lot less noisy than firing the same weapon using the same ammo. So if you fire subsonic ammo like I suggested out of a non suppressed gun then suppress with one of these the sound is very reduced. As to decibels, Inhave no clue, but the first time I witnessed a guy firing through the soda can silencer he put it together in less than 2 minutes, slapped it on a pistol (I think a Browning 22) and shot 5 shots out of it only 20 or 30 feet away from many people walking by on the street and no one even glanced out way. Yeah it made noise but did not sound like gun shots. I was pretty much awed by this simple but rather effective suppresor. It was literally two soda cans taped together in a certain way and shoved over the barrel and the barrel had some tape around it to help make a seal and keep the barrel from being scratched. It was shown to me as a training aid.
I have also seen/heard the soda bottle silencer being used at a police range as part of a demonstration. It was also pretty darned effective with subsonic ammo.
I strongly recommend against making any suppresors unless you are doing it legally somewhere.
