Phase-intensity effects on the ABR.
Auditory brain-stem responses (ABR) to condensation and rarefaction clicks were recorded at six intensity levels in 6 normal subjects. A phase-intensity interaction was apparent for both latency and waveform morphology. These results are in agreement with earlier studies that sampled fewer intensities. The importance of determining both phase and intensity in clinical applications of the ABR is demonstrated in this investigation.
