Abstract

The determination of the sound power of audible noises and their location are usually complicated by room effects, high ambient conditions and frequently the presence of other sources. The two-microphone acoustic intensity approach was found to be a promising technique for analyzing sources of noise where conventional methods are not particularly practical. A procedure is described for measuring directly acoustic intensity levels using a simple `calibrator' and commercial available dual channel analyzer
