Measurement of the Nonlinear Distortions in Loudspeakers with a Broadband Noise
The paper presents application of digital filters for measurement of nonlinear distortion in loudspeakers using Wolf’s method and broadband noise as the exciting signal. The results of simulation of the measurement process for loudspeaker with various nonlinearities of Bl factor and suspension stiffness are presented. The influence of various exciting signals e.g. white and pink noise as well as the parameters of digital filters have been tested. The results of measurement of an actual loudspeaker are also presented.
