DETERMINATION OF SOUND CAUSED BY COMPRESSOR VALVES USING TIME SIGNAL ANALYSIS

Peter Kral, Harald Hackl

Abstract

The measurement of sound levels of noise sources located very closely together – for example the inlet and outlet valve of a piston compressor – is a difficult task. This paper describes a method to evaluate the emitted noise levels of each valve. To achieve precise results, an analysis of the sound pressure level depending on time (time-signal) was done. Signal processing and computations of the measurement results lead to clearer separation of the sound emitted by each sound source (valve).
