Problems of sound insulation and control particularly in areas where there is a high level in exterior noise conditions, resulted in this study to determine approaches to sound control in school construction. After a general discussion of noise problems in school districts and teaching situations, two examples of sound control solutions are described in detail. Major areas occur in classroom arrangement and building materials with sound alternation systems related to roof-ceiling, wall-opening, and air-conditioning. Special emphasis is given to discussing sound measurement, and actual control methods used in the examples, including detail drawings. (MM)
