My neighbors are complaining about the pump powering an airstone in a brine shrimp tank. How I can quiet vibration noises from an air pump and stop them from vibrating through the walls?.
Normally I try to get quiet equipment because I have to listen to it too if it's noisey.
But thing is, I don't want to replace equipment for what is going to be a temp setup, esepcially when I have a heap of older air pumps I can use.
You can try to put the pump on top of a sponge, or folded up towel. The vibrations is probably traveling from your desk/floor to the walls because there isn't anything soft to absorb it.
