Abstract

The difference in the reproduction accuracy of the systems with and without the listener's head in the controlled area when the original sound field and design the inverse filter are recorded is confirmed. The reproduction accuracy for the controlled points on the boundary surface of the controlled area is investigated. Two types of sound pressure signals, with and without a dummy head, in an anechoic chamber, are recorded. The signals in the original sound field and those used for designing the inverse filter are recorded without the listener's head in the controlled area. The difference between the reproduction accuracy of systems for which the boundary surface control principle holds. The reproduction accuracy, averaged over all sound source locations from 0° to 180° and all controlled points under condition 1, is found to be 2.52 dB.
