AB  - A new technique for measuring nonlinear distortion in transducers is presented which considers a priori information from transducer modeling. Transducers are single input-multiple output systems (SIMO) where the dominant nonlinearities can be concentrated in a single source adding nonlinear distortion to the input signal. The equivalent input distortion at this source can easily be derived from the measured sound pressure signal by performing a filtering with the inverse transfer response prior to the spectral analysis. This technique reduces the influence of the acoustical environment (room), removes redundant information and simplifies the interpretation. It is also the basis for speeding up distortion measurements, for the prediction of distortion in the sound field and for the detection of noise and other disturbances not generated by the transducer.
