Early- and middle-aer components to clicks as response indices for neonatal hearing screening.
Early- and middle-component-averaged electroencephalic responses (AER) to monotic clicks at 60, 40 and 20 dB normal hearing level were elicited from 18 carefully selected normal neonates. Grand-composite AERs of the responses from all 18 babies showed stimulus-related configurations at all three stimulus levels. AERs for individual babies were more frequently identified as stimulus-related when poststimulus activity beyond 10 ms was included in response-identification procedures than when only the first 10 ms was observed.
