“…This is consistent with the results obtained in earlier studies [2,10,14]. For very high rates (>100/s), synchronicity might be diminished further, as reflected the reduction of wave-V amplitude because the temporal smearing of the neural activity might ´exceed´ the duration of the effective integration window at the stage of processing where wave-V is generated [9]. Wave-V amplitude might therefore less sensitive to changes in synchronization, so in that terms, the system behaves essentially linearly at stimulus rate up to about 100/s.…”

“…This also suggests why the upward spread of excitation occurs at a lower level for the ER-2 than for the ER-3A earphone. It would be interesting to study these effects quantitatively in a cochlear model similar to the studies by, e.g., Dau (2003) and Junius and Dau (2005).…”

The frequency response and sensitivity of the ER-3A and ER-2 insert earphones are measured in the occluded-ear simulator using three ear canal extensions. Compared to the other two extensions, the DB 0370 (Brüel & Kjær), which is recommended by the international standards, introduces a significant resonance peak around 4500 Hz. The ER-3A has an amplitude response like a band-pass filter (1400 Hz, 6 dB/octave -4000 Hz, -36 dB/octave), and a group delay with "ripples" of up to ±0.5 ms, while the ER-2 has an amplitude response, and a group delay which are flat and smooth up to above 10000 Hz. Both earphones are used to record auditory brainstem responses, ABRs, from 22 normal-hearing ears in response to two chirps and a click at levels from 20 to 80 dB nHL. While the click-ABRs are slightly larger for ER-2 than for ER-3A, the chirp-ABRs are much larger for ER-2 than for ER-3A at levels below 60 dB nHL. With a simulated amplitude response of the ER-3A and the smooth group delay of the ER-2 it is shown that the increased chirp-ABR amplitude with the ER-2 is caused by its broader amplitude response and not by its smoother group delay.

“…They did not, however, yield identical patterns across ears and methods, which is a consequence of the nature of the signals. Whereas ABR wave-V re fl ects neural activity across many fi bers of cochlear and brainstem sites (Junius and Dau 2005 ) , the CEOAE contains information about those cochlear locations where re fl ections from the forward traveling wave took place (Shera and Guinan 1999 ) . The CEOAE suppression patterns thus only contain a subset of frequencies (predominantly in the 1-2 kHz region; Puria ( 2003 ) ) of the synchronously excited region on the BM to a broadband click, leading to higher across-ear-and-subject variability in the CEOAE lag-suppression patterns (Verhulst et al 2011a ) .…”

Normal-hearing individuals have sharply tuned auditory fi lters, and consequently their basilar-membrane (BM) impulse responses (IRs) have durations of several ms at frequencies in the range from 0 to 5 kHz. When presenting clicks that are several ms apart, the BM IRs to the individual clicks will overlap in time, giving rise to complex interactions that have not been fully understood in the human cochlea. The perceptual consequences of these BM IR interactions are of interest as lead-lag click pairs are often used to study localization and the precedence effect. The present study aimed at characterizing perceptual consequences of BM IR interactions in individual listeners based on click-evoked otoacoustic emissions (CEOAEs) and auditory brainstem responses (ABRs). Lag suppression, denoting the level difference between the CEOAE or wave-V response amplitude evoked by the fi rst and the second clicks, was observed for inter-click intervals (ICIs) between 1 and 4 ms. Behavioral correlates of lag suppression were obtained for the same individuals by investigating the percept of the lead-lag click pairs presented either monaurally or binaurally. The click pairs were shown to give rise to fusion (i.e., the inability to hear out the second click in a lead-lag click pair), regardless of monaural or binaural presentation. In both cases, the ICI range where the percept was a fused image correlated well with the ICI range for which monaural lag suppression occurred in the CEOAE and ABR (i.e., for ICIs below 4.3 ms). Furthermore, the lag suppression observed in the wave-V amplitudes to binaural stimulation did not show additional contributions to the lag suppression obtained monaurally, suggesting that peripheral lag suppression up to the level of the brainstem is dominant in the perception of the precedence effect.
