AB  - Aside from frequency response, loudspeaker distortion measurements are perhaps the most commonly used metrics to appraise loudspeaker performance. Unfortunately the stimuli utilized for many types of distortion measurements are not complex waveforms such as music or speech, thus the measured distortion characteristics of the DUT may not typically reflect the performance of the device when reproducing usual program material. To this end, the topic of this paper will be the exploration of a new multi-tone sequence stimulus to measure loudspeaker system distortion. This method gives a reliable estimation of the average nonlinear distortion produced with music on a loudspeaker system and delivers a global objective assessment of the distortion for a DUT in normal use case.
