This paper presents transducer nonlinearity analysis in view of compensation of these effects. We describe an experimental method of weak nonlinearity characterization, based on a representation of the nonlinearity by Volterra series and using multitone excitations. Device linearization can be achieved by applying the inverse nonlinearity upstream of the device, on the condition that the nonlinearity law is known. To address the need to distinguish nonlinear effects from linear distortions, an ad hoc experimental method has been developed. The characterization of a weakly nonlinear electroacoustic device with usual methods of measurement (THD, intermodulation) does not illustrate the nonlinearities themselves, but only some of their effects. This is the reason why this characterization method was developed.
