Ostergaard Acoustical Associates provides building acoustics services to architects, planners and users to assure good hearing conditions and the control of noise and vibration.

	Site Noise Evaluation We carry out studies and acoustical measurements to determine the potential noise impact of noise sources, such as vehicles and aircraft and to ascertain compliance with noise codes. We then identify the implications for building layout and construction and clearly and concisely communicate this information to the client.
	Room Acoustics Interior finish materials and their placement significantly affect hearing conditions. For example, the room acoustics for an auditorium in natural voice reinforcement and appropriate reverberation, while privacy is the goal for open offices. Ostergaard Acoustical Associates assists with room acoustics criteria, analyses and recommendations. Follow-up testing is also available to evaluate the resulting environment.
	Sound System Design We provide sound system designs compatible with the overall acoustical design, including specifications, contract drawings, check out, and adjustment to assure effective sound systems. Designs include sound reinforcement and playback systems for auditoriums, and masking sound systems to improve privacy in office areas.
	Sound Isolating Construction It is necessary to control the travel of sound for privacy, good hearing and acoustical comfort. We provide analyses to determine the necessary acoustical performance of wall, ceiling and slab constructions. Construction descriptions, specifications, details and inspection and provided to assure effective sound isolation.
	Mechanical System Noise and Vibration Control Noise from mechanical systems travels through duct work as well as through walls and floors. We establish noise criteria for each space and prepare preliminary guidelines for the mechanical engineer. The mechanical design is analyzed; recommendations and specifications and prepared for those mechanical design revisions necessary to assure that the noise criteria are met.
