I have a pool pump outside of the house, sitting on a concrete block which
is on top of a concrete pad. During the day when the pump is on, I can hear
it in the room which is on the other side of the exterior wall.
What is the best way to cut down of the noise?
If I cut two slices of styrofoam and put one on top and one on bottom of the
concrete block will it reduce the noise significantly?
Or do I need to take some drastic measure to build some sort of an enclosure
for the pump?
