“…It should be noted that elevated 1-kHz ABR thresholds occurred with both the Blackman ABR and the linear NN ABR, suggesting that the place specificity is similar for both stimulation protocols. This finding is consistent with previous research suggesting no difference in the place specificity of Blackman-and lineargated tone bursts (Oates & Stapells, 1997a, 1997b. The finding that high-frequency cochlear regions contribute to low-frequency responses is not surprising and is consistent with the upward spread of excitation that has been observed in mechanical and neural response measurements in animal models (e.g., Kim, Chang, & Sirianni, 1990;Pfeiffer & Kim, 1975;Robles & Ruggero, 2001;Rose, Hind, Anderson, & Brugge, 1971) as well as in DPOAE suppression (e.g., Gorga, Neely, Dorn, Dierking, & Cyr, 2002) and psychophysical masking experiments (Egan & Hake, 1950;Wegel & Lane, 1924) in humans.…”

Both the ABR and the ASSR provided reasonably accurate predictions of behavioral threshold across the three subject groups. There was no evidence that the predictive accuracy of the ABR evoked using Blackman-gated tone bursts differed from the predictive accuracy observed when linear-gated tone bursts were presented in conjunction with notched noise. Similarly, there was no evidence that the predictive accuracy of the AM ASSR differed from the AM/FM ASSR. In general, ABR thresholds were recorded at levels closer to behavioral threshold than the ASSR. For certain individuals with steeply sloping hearing losses, the ASSR may be a more accurate predictor of behavioral thresholds; however, the ABR may be a more appropriate choice when predicting behavioral thresholds in a population where the incidence of normal hearing is expected to be high.

“…The derived-band center frequency was designated as the lower HPN cutoff frequency in the subtraction procedure. There is some controversy concerning the designation of the center frequency of the derived band ͑discussed in detail by Oates and Stapells, 1997b͒. Several earlier studies chose the lower HPN cutoff frequency as the center frequency based on subtractions of HPN acoustic spectra ͑Don and Eggermont, 1978;Don et al, 1979;Eggermont and Don, 1980;Oates and Stapells, 1997b;Nousak and Stapells, 1992͒.…”

“…Presenting HPN masking at different cutoff frequencies together with stimuli may be used to limit the cochlea's response. Subtractions can then determine ''derived responses'' that reflect the activation of the cochlear regions between the two cutoff frequencies of the HPN ͑Don, Eggermont, and Brackmann, 1979;Eggermont, Spoor, and Odenthal, 1976;Nousak and Stapells, 1992;Oates and Stapells, 1997b;Ponton, Don, and Eggermont, 1992;Stapells et al, 1994͒. Place specificity of ASSRs to AM tones is still under investigation. Early ASSR studies, using AM tones modulated between 40-50 Hz, revealed good place specificity by estimating behavioral thresholds in hearing-impaired individuals and by using high-pass noise masking techniques ͑Griffiths and Chambers, 1991; Kuwada, Batra, and Maher, 1986͒.…”

Auditory steady-state responses (ASSRs) were elicited by simultaneously presenting multiple AM (amplitude-modulated) tones with carrier frequencies of 500, 1000, 2000, and 4000 Hz and modulation frequencies of 77, 85, 93, and 102 Hz, respectively. Responses were also evoked by separately presenting single 500- or 2000-Hz AM tones. The objectives of this study were (i) to determine the cochlear place specificity of single and multiple ASSRs using high-pass noise masking and derived-band responses, and (ii) to determine if there were any differences between single- and multiple-stimulus conditions. For all carrier frequencies, derived-band ASSRs for 1-octave-wide derived bands ranging in center frequency from 0.25 to 8 kHz had maximum amplitudes within a 1/2 octave of the carrier frequency. For simultaneously presented AM tones of 500, 1000, 2000, and 4000 Hz, bandwidths for the function of derived-band ASSR amplitude by derived-band center frequency were 476, 737, 1177, and 3039 Hz, respectively. There were no significant differences when compared to bandwidths of 486 and 1371 for ASSRs to AM tones of 500 or 2000 Hz presented separately. Results indicate that ASSRs to moderately intense stimuli (60 dB SPL) reflect activation of reasonably narrow cochlear regions, regardless of presenting AM tones simultaneously or separately.

“…If several peaks of equal amplitude occurred within this range, then the peak preceding the largest negative shift was selected. Wave V´was defined as the greatest negativity occurring within 8 milliseconds after wave V. [32][33][34] MLR wave Na was defined as the largest negativity occurring between 10 and 30 milliseconds, and wave Pa was defined as the largest positivity after wave Na. Latency values were corrected for the delays introduced by the insert earphones.…”

Relations among Auditory Brainstem and Middle Latency Response Measures, Categorical Loudness Judgments, and Their Associated Physical Intensities

This study characterizes changes in response properties of toneburst-evoked auditory brainstem responses (ABRs) and/or middle latency responses (MLRs) as a function of perceived loudness and physical intensity of these stimuli and delineates the range of levels corresponding to categorical loudness judgments for these stimuli. ABRs/MLRs were recorded simultaneously to 500- and 2,000-Hz tonebursts in 10 normal-hearing adults at levels corresponding to each listener's loudness judgments for four categories on Contour Test of Loudness. Group mean ABR wave V and MLR wave Pa latency values increased significantly as loudness judgments decreased. Group mean amplitude values for ABR wave V-V' and MLR wave Na-Pa increased as the listeners' categorical judgments increased. Listeners assigned a broad range (30 to 40 dB) of stimulus intensities when judging loudness of these stimuli within a specific loudness category. This was true for all four loudness categories and both frequencies. Thus, it appears that tone-evoked ABR/MLR response measures reflect, in part, the listener's perception of loudness. Response latencies are a more sensitive indicator of listener's loudness percept than corresponding response amplitudes. An appreciable range of signal levels was judged to be categorically equivalent across listeners. Thus, limiting how loudness judgments can be applied to prescriptive hearing aid fittings in individuals who cannot provide accurate loudness judgments.
