Abstract: A perceptually-driven distortion metric for loudspeakers is proposed that is based on a critical-band spectral comparison of the distortion and noise to an appropriate masking threshold. The loudspeaker is excited by a sine-wave signal composed of windowed 0.3 second bursts. Loudspeaker masking curves for sine waves between 20–500 Hz are derived from previously published ones for headphone distortion evaluation and expanded to curves at 1 decibel increments by linear interpolation and extrapolation. For each burst, the ratios of measured distortion and noise levels to the appropriate masking curve values are determined for each critical band starting at the second harmonic. Once this is done the audibility of all these contributions are combined into various audibility values.
