I keep my 60 gallon in the living area just outside my bedroom. The air pump was also driving me nuts, so I connected the air-pump to the same time-switch as the lights. When the lights go out, the air-pump stops. When I first did this, I was expecting the fish to be gasping at the top of the tank the next morning, but they were fine.
The canister filter runs 24/7 though, and it seems that the spray-bar from the filter creates sufficient turbulance on the surface to enable the fish to survive during the night without the air-pump.
