Abstract Details

1979, Doctor of Philosophy (Ph.D.), Bowling Green State University, Communication Studies.
Normative data were collected for a recently discovered slow negative brain stem response occurring at 10 ms (SN10) after an auditory stimulus. The usefulness of SN10 as an indicator of threshold sensitivity in 20 normal newborns was investigated. Responses were elicited for tone pips of 500, 1000, 2000 Hz and a broad spectrum click at 60, 40, and 20 dB re: normal hearing level. Response latencies were measured from the auditory brain stem recordings. Results suggested that the SN10 response varied systematically as a function of frequency and intensity of the stimulus. Latencies decreased as frequency and intensity increased. Newborns also demonstrated significantly longer latencies for all stimuli as compared to an adult control group. This age difference indicates that the generator source for SN10 continues to develop after birth. Overall results suggested that SN10 is a reliable indicator of hearing sensitivity for frequencies of 1000 Hz and higher. Previously reported usefulness for 500 Hz was not substantiated.
