Otoacoustic Emissions (OAE) and Auditory Brainstem Response (ABR) play important roles in the processing information of the auditory perception. Most previous studies only measured one signal simultaneously. When com- paring the features between the signals, the testing conditions might be changed, lacking of proofs to ensure the integrity and coherence. Based on the integrated detection system of auditory propagation pathway, the OAEs and ABRs were measured simultaneously in normal subjects under different intensity and frequency of click and tone burst stimulation. The model to simulate the TEOAEs latency-frequency function was built up, and the latencies between OAEs and ABRs were further compared.
