The previous work reported on the use of modulated musical multitone (MMM) for the detection of audible distortion in horn drivers. With an adjustable crest factor, MMM is designed to match the properties of music and is used to measure nonlinear distortion audibility thresholds. In this work, the signal is used to create a distortion profile of two-way systems for comparison. The MMM reaction is post-processed to obtain the Multitone Total Nonlinear Distortion response, which presents nonlinear distortion products averaged in a “sliding window” in the frequency domain. MTND responses are derived from a low level to a very high level. These MTND curves are compiled into a comprehensive spectral distortion profile which can be used to compare multiple systems.
