A level-increment detection task isolates sensitivity to brief loudness changes.

Evidence

LEVEL Task In a 2I-2AFC trial, the listeners were required to indicate an interval containing a 400-ms-long SSMC or a transposed stimulus whose central 200-ms portion (including 20-ms raised-cosine ramps) was incremented in level by ΔL dB, while the other non-signal interval contained an original SSMC or a transposed stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1046
