So I live in a rural subdivision. I shoot CCI quiets and 22 shorts out of my 22 rifles out the back yard in my wooded creek area, no complaints. While most of my neighbors know if they hear a gunshot, it’s probably me, but I want to keep a good relationship with them. My local range is 10 miles or 20 minutes away. Sometimes I just need to test a few rounds. At first I just cracked my detached garage entry door and fired a few shots. Wife could hear them from inside the house. So I added an empty cardboard barrel. Now she says it sounds like a muffled pop. I just tested a 44-40 rifle and revolver. With the revolver, it’s important to get the front of the cylinder inside the barrel for more sound deadening.
