An Algorithm for Analysis of Phase Effects: Application to Monaural Distortion Product Estimation
John Erdreich, T. Dean Clack · The Journal of the Acoustical Society of America · 1972
Estimation of aural harmonic magnitudes with the tone-on-tone masking paradigm requires calculation of the monaural phase amplitude effect from measurements of threshold level tones. Such amplitudes have been approximated with a sinusoid but may be more precisely determined by fitting the data with the circle, Ar2 = Ae2+A12−2AeA1 cos(ψ). An algorithm for this procedure is detailed.
