The band-widening paradigm measures signal threshold while varying masker bandwidth

Evidence

Rather than measure the masking effects of a fixed masker and varying the frequency of the signal being detected, Fletcher fixed the frequency of the signal and measured the signal’s threshold in the presence of different maskers. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 473
