A
sound baffle is a construction or device which reduces the strength (level) of
airborne sound. Sound baffles are a fundamental tool of
noise mitigation, the practice of minimizing
noise pollution or
reverberation. An important type of sound baffle is the
noise barrier constructed along
highways to reduce sound levels at properties in the vicinity. Sound baffles are also applied to walls and ceilings in building interiors to
absorb sound energy and thus lessen reverberation.
