Abstract:

The masking effect of a broad-band noise, a sinusoidal tone, or both may be represented in a simple three-dimensional space. The space shows performance as a function of 1 the level of the sinusoidal components relative to the noise, and 2 the relative energies in the signal plus sinusoidal masker waveform and the waveform of the sinusoidal masker alone. Results that appear complex in other representations appear straightforward in this space. For example, over wide ranges, neither frequency and duration of the signal nor the relative interaural phase of the signal and masking stimuli affects the shape of the space, but produces, at most, only a simple translation. Several theoretical descriptions of the space are discussed. Author
