Abstract

Previous papers 1, 2 have discussed the effects of loudspeaker alignment and resonances on the accuracy of reproduction of low frequency audio signals, and a system of modulation transfer function (MTF) measurement was developed which incorporated both the time and frequency domain information into a single measure of response accuracy. The aim of this paper is to extend the previous work into the listening rooms and to assess the degree of information loss which may be incurred as the sound travels across rooms with different modal characteristics.
