Objective: To determine the influence of auditory stimuli spectral characteristics on cortical 30 auditory evoked potentials (CAEPs). 31
Design: CAEPs were obtained from 15 normal-hearing adults in response to six multi-tone 32 (MT), four pure-tone (PT), and two narrow-band noise (NBN) stimuli. The sounds were 33 presented at +10, +20 and +40 dB above threshold, which were estimated behaviorally 34 beforehand. The root mean square (RMS) amplitude of the CAEP and the detectability of the 35 response were calculated and analyzed.
