Measurement of Panel Reflection Using Acoustical Scale Modeling Techniques

Authors: Ortega, Jose C.

AES Convention 89 · Paper 2994 · September 1990

Abstract

The importance of early reflected sound from sidewall and ceiling reflecting panels in auditoria and spaces used for musical presentation has been recognized for some time. Experience teaches that size, shape and orientation of panels affect their reflecting characteristics. This paper presents results of ongoing studies using scale modeling techniques. The measured reflection transfer function is presented for several types of reflecting panels. Transfer functions measured in the shadow zone of a reflecting panel exhibit interference characteristics. The non-uniformity of the transfer functions is shown to be due to out of phase waves diffracted from the panel edges.
