Binaural masking-level difference measures hearing improvement from interaural stimulus asymmetries

Evidence

The BMLD is that difference in just-audible test-tone level that appears when the presentation of signal or masker to one of the ears is changed. There are many stimulus conditions possible because of the two signals, one at each ear, and also the two masker conditions. Most often, the phases of the maskers are equal at the two ears while the phase of the signal is zero at one ear and inverted at the other. The opposite condition, i.e. maskers different and signals identical at the ears, is also used. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1634
