title: Effects of the bandwidth and level of noise and of the duration of the signal on binaural masking-level differences.
abstract: An investigation of the effects of the level and bandwidth of the masking noise and of the effect of test-tone duration on binaural masking-level differences (BMLDs) has been carried out using the standard Békésy audiometric techniques. The BMLDs increase in magnitude with increasing masker level, reach a shallow maximum at bandwidths of the masker near 30 Hz, and scarcely differ for signal durations of 20 and 200 ms. Most of these data are consistent with previously reported results and are to be used in related studies with the same observers.
