How quiet is it really?

I'm fascinated that a firearm can be as quiet as a moderated airgun. Anyone else?
Actually I will be doing another video when I get the chance to . I didn't get it on video but take that same suppressor and put it on a bolt action 22 with the same round it has half the sound of the air rifle and the 10/22. I was shocked and I instantly went out an bought the Ruger American bolt action 22 and a suppressor. Which the suppressor is still in jail waiting on the Alphabet org to approve it. I Should have it by June crazy quiet I probably won't have the Air gun anymore by then but the 10/22 that we used that day will be there and we will do that side-by-side comparison.
 
Enjoyed the video! It's all apples and oranges to me. All airguns are backyard friendly at my house. I can also shoot my 1895g in my backyard. That said, I appreciate quiet and the quieter it is the better I like it. Quiet makes my wife happy and that improves the quality of my life. 😊 That's why I always click on threads with titles like yours.

My ears say that my quietest pcp is wearing a 3d printed mod designed by Subscriber who is a member here.

My Notos wears one of Subscribers mods too. Lovely sound reduction.
