A note on the influence of the averaging time and the frequency resolution on the accuracy of acoustic measurements

Research output: Book/Report › Book › Research › peer-review

Abstract

This note deals with measurement accuracy in some typical acoustic measurements, measurement of sound pressure and sound intensity in one-third octave bands, and measurement of acoustic transfer functions with a multi-channel FFT analyser. The purpose is to demonstrate by simple examples how the choice of measurement parameters can affect the accuracy of an acoustic measurement, and how the accuracy with a given set of parameters depends on the measurement conditions.
