Ostergaard Acoustical Associates services

Ostergaard Acoustical Associates provides architectural acoustics services to assure appropriate hearing conditions and the control of noise and vibration.

Environmental noise control has as its objective the control of outdoor noise.  Ostergaard Acoustical Associates conducts community noise surveys and noise exposure studies for existing or proposed land uses, prepares environmental impact statements concerning noise exposure, assists with the development of noise legislation or zoning codes, and develops methods to reduce environmental noise.

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.

The Interrelation of Acoustics and the Law: Questions about acoustics frequently arise in land use planning, product liability, workman’s compensation, and compliance with local and federal land use regulations. Ostergaard Acoustical Associates provides information and support in all of these areas.  The type of scientific guidance appropriate to each area is different.
