摘要：

Our previous work has demonstrated the feasibility of recording evoked otoacoustic emissions (EOAEs) using maximum length sequence (MLS) techniques. New equipment has been constructed, using standard DSP boards and computers, which permits stimulation at much higher rates. The technical aspects of analogue-to-digital converter (ADC) requirements, stimulus problems, artefacts, signal-to-noise (SNR) computations and MLS application are considered here and illustrated with data from the new system.
