MULTI-MODE AUDIOMETRIC DEVICE AND ASSOCIATED SCREENING METHOD

摘要

A multi-mode audiometric device (20) comprising stimulus generator for transmitting at least one true random stimulus sequence to a subject's inner ear, a first detection member (28) for detecting at least one AEP signal having at least a first waveform, second detection member (26) for detecting at least one OAE signal having at least a second waveform; a signal analyzer for analyzing the AEP and OAE signals, the signal analyzer including a first averager for reconstructing the first waveform and a second averager for reconstructing the second waveform; and a synchronization mechanism for synchronizing the stimulus generator and the signal analyzer. The stimulus generator, the signal analyzer, and the synchronization mechanism are housed within computer (22).
