AB  - By utilizing modern DSP technology and FFT spectral analysis, and by applying some aspects of human hearing and psychoacoustics, a reliable method of rub and buzz distortion testing for loudspeakers can be devised for a wide variety of engineering and production applications. Additionally, test times can be radically reduced, thus contributing favorably to outside noise rejection and a higher degree of repeatability. Examples of test results include comparisons of good and bad units and feature standard cone type loudspeakers and compression drivers showing varying degrees of conformity. In the final analysis, loudspeakers are tested for polarity, frequency response and different types of distortion.
