Noise Control in Buildings

Abstract

In this session, some of the fundamental aspects of noise generation, radiation, and propagation in buildings were illustrated. One novel demonstration was a miniature ripple tank effectively lighted and projected by a standard overhead projector (Baade). The point was emphasized that there is no single current text suitable for use in teaching acoustics to architects (Kingsbury). Illustrations of practical aspects of noise-control engineering were presented in three papers. One discussed the multiplicity of noise control problems in a typical modern architectural project (Kleinschmidt). Another showed that analytical methods may be helpful in practical vibration isolation problems (Champ). A third paper demonstrated that innovative solutions to floor and ceiling isolation problems need not be costly or complex to be effective (Ostergaard). ISO activities related to vibration and building noise control were summarized (Muster). In the area of field testing of floors and partitions, the differences between laboratory and field installations were outlined (Oliphant). It was shown that, by using ASTM E90 in the laboratory and ASTM E336 in field tests, results were essentially the same. In the closing paper, Kodaras stressed the type and nature of training necessary for municipal officials and inspectors to enforce a modern building code.
