Electroacoustic Free-Field Measurements in Ordinary Rooms--Using Gating Techniques

Authors: Møller, Henning; Thomsen, Carsten

AES Convention 52 · Paper 1062 · October 1975

Abstract

By the use of gating techniques, many types of acoustic measurement normally confined to anechoic rooms, can now be made in ordinary reflective rooms. Of primary importance are the measurements of loudspeaker frequency response and directional characteristics. However, the technique is also applicable to other areas such as measurement of distortion, early reflections, absorption, and phase response. These measurements are made possible by means of a Gating System which provides the necessary tone burst test signal and measures the peak amplitude of the received signal, which is gated by an adjustable time window to eliminate the influence of reflections and loudspeaker transient distortion.
