Inverse Frequency Dependence of Forward Tone-on-Tone Masking Patterns
Forward tone-on-tone masking patterns were measured at frequencies 0.5, 1.0 and 2.0 kHz and sensation levels 20 dB SL and 60 dB SL in four normal hearing subjects using a modified 2-alternative forced choice procedure. At 60 dB SL the forward masking patterns have flat high frequency slope and steep low frequency slope. At 20 dB SL the forward masking patterns have slopes reversed with reference to their steepness, i.e. a steep high frequency slope and a flat low frequency slope. Thus a reversal of masking patterns is observed which occurs at a level between 60 and 20 dB SL. The data are in agreement with earlier observations on simultaneous masking.
