Have no idea about the Benjamin, but I'd have to "hear" the advertised 70% reduction in noise level compared to a springer to believe it. I have a Theoben Crow Magnum IV with HE gas ram piston power, and it makes plenty of noise when shot. Enough noise that when I used it for pigeon pest control in my yard at my last house I shot it out a slightly open window, but from yards inside the room to help keep some of the noise in the house. Even so my next door neighbors could hear it if anywhere outside. It was not a problem with them, they wanted the pigeons removed as well. I have no idea if those farther away heard it or not though, or knew it was a shot if they did. No LEO's ever came. And that was a ranch house neighborhood on fairly large lots with stone walls and mature landscaping to help hold the noise in. My CM is a 20 cal that does about 1060fps with 24fpe, about a 1000fps faster than the 22 cal Benjamin if that helps any.
