This paper is presented in support of a tutorial on practical.measurement techniques zr acoustic: and audio engineering.The paper provides a deschation of the measurement of the equeney response function ofa system.Motives for describing and measuring the per mnance of reproduced sound systems and components in the frequency domain are reviewed and the 'equeney response ofa linear, time invariant system is introduced by consideration ofsinewave testing.Broadband methods for estimating the equeney response lnction (based upon power spectral estimates) are presented and their practical application and limitations are discussed.
