Abstract

An automated auditory brainstem response (ABR) peak identification and labeling system has been developed and evaluated. The system uses a set of matched filters and a rule base for online peak labeling. The matched filters are designed to reflect the spectral and biphasic characteristics of the ABR peaks. The rules are designed to identify ABR peaks based on the latencies and amplitudes of the peaks found in the matched-filter output buffers. The system is capable of automatic generation of latency-intensity functions. The algorithm was tested using 168 ABRs from four adults, yielding only two incorrectly labeled recordings.
