Real time sound intensity measurements in an industrial complex.
The development of techniques and new tools for environmental acoustic measurements has opened up new ways and means to determine the source location, source ranking and energy flow path. The new tools posses versatile probes for different applications, better digital signal processing facilities and data presentation for sound pressure measurements--the quantity we hear, sound power measurements--the quantity emitted from a source, and the sound intensity measurements--the quantity of propogated sound power. The paper reports the results of real time sound intensity measurement carried out in an industrial complex with a portable sound intensity analyzer equipped with 1/3 octave filters and a dual microphone remote control probe for real time analysis. Extensive sound intensity measurement in the Power Plant, Ammonia Compressor House and Urea Compressor House have been carried out. The results are useful for sound power determination of various sources.
