Measurement of Nonlinear Distortion of low-cost Microphones

Original language description

Measuring of the nonlinear distortion of microphones is affected by nonlinear distortion of the loudspeaker that emits the measuring signal because of serial combination of these two nonlinear systems. This paper describes an application of a method of nonlinear system identification in case of the series combination of two nonlinear systems, where the first one represents the loudspeaker and the second one represents the microphone. The second nonlinear system (microphone) is modeled by Hammerstein model, the coefficients of this model being identified by the method. From these frequency dependent coefficients the frequency dependence of the total harmonic distortion (THD) of the microphone is calculated.
