Time-Domain Nonlinear Modeling of Practical Electroacoustic Transducers
A comparative study of classic and modern time-domain nonlinear modeling techniques is presented for the case of loudspeakers. NARMAX modeling, as well as some modern methods, employing artificial neural networks, fuzzy logic, and their combinations, are applied using measured time-series input-output data. The comparison is performed on the basis of their ability to produce accurate but also adequate and parsimonious nonlinear loudspeaker models, as well as of the simplicity of their application. Both stationary random and real musical signals are used in the evaluation.
