Abstract

Sound intensity measurements are being increasingly used to determine sound power of noise sources. Assessment of measurement uncertainties is important for wider use of this technique. This paper summarizes a recent study carried out to examine the bias and random errors associated with the scanning intensity technique under complex acoustic field conditions.1 Based on experiments and theoretica! formulations, errors were calculated for a complex acoustic source. Measurement errors under extraneous noise conditions were also examined.
