Discussion of the parameters governing noise control and room acoustics are followed by a demonstration on how to achieve a good acoustical environment. Topics emphasized include--(1) design and control objectives, (2) noise sources and propagation, (3) reverberation parameters, (4) noise control factors and parameters, and (5) sound systems. Also…

This review surveys documents and journal articles previously announced in RIE and CIJE that deal with the principles and techniques of sound transmission and control, particularly as they relate to school environments. School planners and administrators are advised that excessive acoustical insulation costs may be avoided by early decisions…

Various factors of the classroom environment that can contribute to a more complete learning atmosphere are explored. The author presents a review of certain research findings that may serve as guidelines in the development of an environmentally coordinated classroom. The importance of providing a classroom which promotes a multisensory approach…
