Abstract
Middle-component AERs (8–90 msec) to tone-pips from 10 normal-hearing adults were subjected to three objective methods of response identification. Threshold was then determined for each subject according to four different rules. The criterion score, which considers conjointly latency and amplitude values across the middle-component peaks, was developed as a single-value measure for response-identification and subsequent threshold-determination procedures. One of the response-identification methods was applied to 10 hearing-impaired subjects; the results of the threshold-determination procedures were encouraging. Further directions toward improving objective response analysis are discussed.
