Prudent Aire’s Rectangular Silencer are designed for silencing noise transmitted through ductwork, utilize sound absorbing media to reduce sound levels. As the discharge noise passes through the silencer, the acoustic energy enters the baffles through the holes in the internal perforated plate. This perforated plate protects the acoustic media from being eroded by the air at high velocities, but have a large enough free are to be acoustically transparent. Once inside the baffle, the acoustic energy interacts with the absorptive media, the friction between the acoustic energy and the fiber glass converts the acoustic energy into heat, thereby reducing the amount of acoustic energy and decreasing sound levels at discharge of the silencer.
