30 odb on huben

Not sure about the 0db noise level, but i can tell you i have the Huben .25 LE that i have put a DFL .25 Sumo on and it does quiet the report snap a smidge...
Now keep in mind there Will still be a snap at your ear from the gun , that is the air sending the projectile down the barrel.
I personally find the Huben a quiet gun without the added moderator, My Impact .22 cal is MUCH louder without the Sumo than the Huben in stock form, i only stuck the Sumo on the Huben 1 time to see the difference and have since shot it in stock form..

The best advice i can give you is have someone else shoot your Huben while you stand to the side, you will be surprised how quiet it really is
