Architectural acoustics noise control practices include interior sound reverberation reduction, inter-room noise transfer mitigation, and exterior building skin augmentation. In the case of construction of new (or remodeled) apartments , condominiums , hospitals , and hotels , many states and cities have stringent building codes with ...
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
It prohibits construction and demolition within 500 feet of noise sensitive properties (residences included) if the equipment sound control devices are less effective than the original equipment and if noise mitigation measures are not used when the levels exceed 90 dB (weighting not specified) or more than 80 dB during the day for three days.

Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound.In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations.
In July 2007, New York City’s Department of Environmental Protection promulgated rules concerning citywide construction noise mitigation. These new rules reward contractors deploying tools and machinery that use the best available noise control technologies, are designed for quiet, or are known to be the quietest available models of their type.
