Level dependence of click-evoked responses. Data from monaural stimulation. A: when the stimulus level decreased (numbers on left side refer to attenuation in dB), the shape of the waveform remained oscillatory, the amplitude decreased and the response occurred at longer latencies. However, as indicated by the vertical line, the position of the response maxima remained stable. Scale bar: 10 mV. B: level dependence of delays in the pooled data of 72 data sets. Stimulus amplitudes were decreased from 0- to 20-dB attenuation. To determine the changes in phase or group delay induced by changes in click level, the times of arrival of the respective response extrema evoked by the different click intensities were picked from the mean curves and subtracted from each other. For phase delay values, this sometimes included jumps between peaks as explained in the text. Each difference provided a data point for the histograms. —, group delay; (...), phase delay. Bin widths: 20 µs for the phase delay and 40 µs for the group delay.
