Detection of nonlinear distortion in audio signals
IEEE Transactions on Broadcasting, 2002Nonlinear distortion of a signal passing through a system may be caused by a number of factors. One of those factors, a limiter like transfer function, is considered. The nonlinear distortion causes a change in the probability density function (PDF) of the signal.

Identification of linear systems in the presence of nonlinear distortions
IEEE Transactions on Instrumentation and Measurement, 2001This paper treats the identification of linear systems in the presence of nonlinear distortions. It extends the theory developed for measurement setups where the input is exactly known and the output is observed with errors (output error framework) to measurement setups where both the input and output are observed with errors (errors-in-variables ...

The nonlinear distortion of directional loudspeaker
2008 International Conference on Audio, Language and Image Processing, 2008A directional audible sound could be generated from the nonlinear interaction of ultrasound in the propagation medium. The demodulated audible signal is proportional to the second time derivative of the square of the ultrasound envelope, described in Berktaypsilas Far-field solution, which is nonlinear to the process of sound reproduction.

Signal Distortion in Nonlinear Feedback Systems
Bell System Technical Journal, 1963This paper reports on some properties of the solutions to the functional equation $s_{2}(t) = \varphi[{\bf C}s_{2}(t) + s_{1}(t)],$ where ϕ is a nonlinear function, the operator C is a convolution, and s 1 is a known function belonging to a prescribed Banach space.

"Apparent bass" and nonlinear distortion
IRE Transactions on Audio, 1961A discrepancy between the "apparent bass" response heard by the average music listener and anechoic-chamber measurements has been noted for some small loudspeaker systems. This may be caused by the psychoacoustic response to the generation of harmonic distortion by the nonlinear suspension and the inhomogeneous flux gap density in a small speaker.
