Determination of a Low Frequency Noise Source's Parameters by a Space Intensity Sensor

Abstract

The aim of this paper is to present the basic equations and the first results of an experimental investigation using the space intensity sensor. We offer a multi-element acoustic sensor that gives the opportunity to find the source's parameters (distance between the observer and the source, direction to the source, power of its radiation, its multipole type). It is very important for the diagnosis of natural low frequency sources. The results of the measurements of the sound multipole source's parameters are presented. The test's experimental data correspond well to the real controlled parameters.
