    Research output: Book/ReportBookpeer-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.
