an cause fatigue in exposed individuals, lower efficiency and productivity, impaired speech communication, and hearing loss. Excessive noise is almost everywhere today - in the office, in schools, hospitals and other institutional facilities, in all classes of public buildings, and in our factories.

Sound Absorbing Materials,and sensitive, material types are innumerable. Complicating matters further, some materials are used extensively at all three locations in the noise equation, namely the source, path and receiver. For this reason we have chosen to categorize material types as follows:

Office Acoustics,ith lighting, HVAC, fire safety, and power and signal distribution for a safe, efficient and cost-effective office environment. Heralded as the wave of the future over 10 years ago, a design methodology utilizing a systems concept is imperative in today’s demand for optimum speech privacy.

Vibration Isolation Materials,er frequencies but they permit a great transmission of vibration at the resonant frequency of the system. The addition of damping will limit the response at the resonant frequency but may also reduce the isolation capability at the higher frequencies.
