Two-dimensional SNR-importance functions are needed to model filtered-source intelligibility

Evidence

Further work needs to be done to determine ceiling and floor values in narrower frequency bands. To model these results, SNR-importance functions also need to be built, for example following the approach of Studebaker and Sherbecoe ( 2002 ) who proposed a two-dimensional importance function. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3585

• QUESTION: Worth chasing: what exactly is Studebaker and Sherbecoe’s two-dimensional importance function, and could it be adapted for narrower bands?
