The paper addresses the relationship between nonlinear distortion measurement and nonlinearities which are the physical causes for signal distortion in loudspeakers, headphones, micro-speakers and other transducers. Using simulation techniques characteristic symptoms are found for each nonlinearity and presented systematically in a guide for loudspeaker diagnostics. This information is important for the interpretation of nonlinear parameters and for performing measurements which describe the loudspeaker more comprehensively. The practical application of the new techniques are demonstrated on three different loudspeakers.
