NOISE CONTROL FOR INDUSTRY
OAA consults to industrial clients to reduce noise radiated to the community as well as to the hearing zones of employees.
After gaining an understanding of the mechanisms and individual sources producing excess sound, preference is given to noise control techniques that reduce noise production. Alternatively, methods are identified to reduce sound travel along the path between the noise source and receiver. Specifications for noise control hardware, such as acoustical barriers or silencers, are developed as needed.
Acoustical measurements and modeling are important tools used by OAA for assessing the strength of noise sources, understanding how multiple sources sum up at the receiver, and evaluating the effectiveness of installed noise control measures.
