Problem:
Compressor and fan noise emanating from an outdoor condenser typically located adjacent to an exterior wall. The noise levels are compounded by the sound reflecting off this wall. Noise levels become unacceptable in the spring and fall especially when neighbors have windows open and it is warm enough for the condensers to start up.

Solution:
A outdoor sound curtain enclosure of surrounding the air compressor. Typically two, three, or four sided enclosure of sufficient height with an open top silenced ventilation options (depending on the application).
