Sound Intensity Measurement for Characteristics of Two Microphone Arrangements.

두 개의 Microphone 배열 특성에 의한 음향 Intensity 측정

The errors caused by developmental finite difference approximations in the two microphone acoustic intensity measurement technique are considered in this paper. The frequencies and pressure responses obtained experimentally, are presented for both face to face (FF) and side by side(SS) microphone configurations. The implications of these results by the use of such a cofiguration for two microphone sound intensity measurement are discussed.
