Acoustical Modeling as a Tool in Problem Solving

Authors: Beranek, Leo L.

Journal of the Audio Engineering Society · Volume 17 · Issue 2 · pp. 151–155 · April 1969

Abstract

Scale modeling as a means of predicting full-scale performance is in widespread use today. It affords a means of investigating interrelations among design parameters on an inexpensive, small, working replica of the full-scale device and is a vital tool in design. This paper illustrates some techniques of scale modeling in three areas of acoustics-acoustics of rooms, noise production of jets, and vibration in structures. Dynamically similar systems are developed using the methods of dimensional analysis. Photographs of scale model auditoriums and illustrations of data are presented.
