Frequency importance varies nonlinearly across signal-to-noise ratios

Evidence

Studebaker and Sherbecoe ( 2002 ) derived intensity importance functions from intelligibility scores in five frequency bands. The functions they obtained differed from the one used in the SII calculation. Their functions are frequency-dependent and nonlinear along SNRs, which is in agreement with the findings of the present study. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3581
