“…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. Although these results seemed promising for using ASSRs in a clinical setting, the 40-Hz response was found to be inconsistent and unreliable in infants ͑Aoyagi et Maurizi et al, 1990;Stapells et al, 1988;Suzuki and Kobayashi, 1984͒. Modulating AM tones between 70-110 Hz can evoke stable ASSRs in infants and adults, whether sleeping or awake ͑Aoyagi et Cohen, Rickards, and Clark, 1991;Levi, Folsom, and Dobie, 1993;Lins et al, 1995;Rickards et al, 1994͒.…”

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.

“…In adults, ASSR amplitude is characterized by a strongly dominant peak relative to the noise fl oor near 40 Hz (Cohen et al, 1991;Galambos et al, 1981;Kuwada et al, 2002;Kuwada et al, 1986;Levi et al, 1993;Linden et al, 1985;Picton et al, 1987;Rees, 1982;Rees et al, 1986;Ross et al, 2000;Stapells et al, 1984Stapells et al, , 1988Suzuki & Kobayashi, 1984), with additional peaks at lower values of F m between 10 and 20 Hz (Ross et al, 2000;Stapells et al, 1984), and at higher values of F m between 80 and 110 Hz (Cohen et al, 1991;Kuwada et al, 2002;Lins et al, 1995;Rees, 1982;Ross et al, 2000 (Alaerts et al, 2009;Picton et al, 1987;Rees, 1982;Rees et al, 1986), this area has not been investigated thoroughly. Upon the assumption of the general correspondence -between transient-AEP latency windows and periods of ASSR componentsa transient rate-based profi le was created based on the AEP literature (Aoyagi et al, 1993;Jiang et al, 1991;Lasky, 1984;Martin et al, 1988;Salamy et al, 1978Salamy et al, , 1982Tucker & Ruth, 1996).…”
