FIG. 3.

Estimates of cochlear delays in humans based on derived-band CAPs and BSERs. A Estimates from CAPs: from Figure 4 of Elberling (1974), Figure 5 of Eggermont (1979), and Figure 3C of Schoonhoven et al. (2001). Estimates from BSERs: Figure 4 of Eggermont and Don (1980). Click levels were as follows: Elberling (1974), 95 dB p.e. SPL (i.e., “baseline-to-peak pressure corresponding to that of a tone with rms pressure of 95 dB SPL”); Eggermont (1979), 90 dB p.e. SPL; Schoonhoven et al. (2001), 98.4 p.e. SPL. The BM delay estimates of Eggermont (1979) and Schoonhoven et al. (2001) were calculated in the original publications on the assumption that synaptic/neural delays amount to 0.8 ms. The delays estimated by Elberling (1974) were not corrected for synaptic/neural delays in the original publication and are presented here after subtraction of 0.8 ms. B All conventions as for A, except that the derived-band measurements are presented relative to the minimum delay for each series of measurements.
