Building noise control
Acoustical engineering has contributed signifcantly to making buildings and manufacturing plants more confortable to the human ear. It has also enabled owners to build facilities with diverse acoustic environments close to one another. Noise generated from mechanical equipment that finds its way into occupied areas may be annoying to people, depending on its characteristics. This paper describes the terminology used to discuss acoustical problems as well as the properties of sound. Characteristics of noise generated by typical heating ventialted, and air conditioning equipment are presented as well as an analysis of noise in a particular ducted system. Methods to reduce noise in ducted systems include source reduction and system modification. 6 refs., 1 fig., 7 tabs.
