Bo I think you made the right choice with the Gamo whisper. Like 76chevy they are quiet.

I wish I had chose on of those when I bought mine.I was looking more for speed, I had purchased the Ruger Air Magnum, man is that thing loud and its like 76chevy its shoots in the 1300's with ease.
Over the years I have had a few

The rifle at the top was my first pellet rifle that my uncle gave me some where around 1974, it is a Slavia 618 177cal
The next one is also a Slavia 622 22cal
Then I have 3 Crossman 760's, one of them is the first pellet rifle that I purchased myself in 1976, I have it disassembled reworking it.
The orange one is some Chinese model that I picked up at a garage sale for 5$
Then the bottom one is the Ruger Air Mag
