Figure 1.

A detection pattern for the average listener comprises hit and FA rates for each wideband (2900-Hz bandwidth) dichotic reproducible waveform averaged across six individual listeners. The x axis shows the index of the reproducible waveform. Insets show examples of the dichotic tone-plus-noise at left (N + T) and right (N − T) ears and the diotically presented noise-alone (N) waveforms for reproducible noise waveform number one (data from Evilsizer et al., 2002 and two listeners tested recently). The tone was added at the average threshold level of the six listeners, and the spectrum level of the noise was 40 dB SPL.
