  • Title: Electrophysiologic assessment of low-frequency hearing: sedation effects.
    Author: Palaskas CW, Wilson MJ, Dobie RA.
    Journal: Otolaryngol Head Neck Surg; 1989 Oct; 101(4):434-41. PubMed ID: 2508020.
    Abstract:
    Sixteen normal-hearing adults were tested in both awake and sedated states for several evoked responses to low-frequency stimuli. Responses obtained by cross-correlation function, middle latency responses, and the 40-Hz response proved most sensitive; all had mean thresholds of less than 20 dB normal hearing level for the awake-alert state, but 40-Hz and middle latency response mean thresholds were shifted about 10 dB under sedation. The cross-correlation method seems to offer promise for pediatric auditory assessment.
