Abstract: This paper investigates the influence of nonlinear components that contaminate the linear response of acoustic transducers and presents a method for eliminating the influence of nonlinearities in acoustic measurements. The method is evaluated on simulated as well as experimental data and is shown to perform well even in noisy conditions. The limitations of the Total Harmonic Distortion, THD, measure is discussed and a new distortion measure, Total Distortion Ratio, TDR, which more accurately describes the amount of nonlinear power in the measured signal, is proposed.
