Evaluation of transducers for obtaining intraoperative short-latency auditory evoked potentials.
Operative monitoring of short-latency auditory evoked potentials during posterior fossa surgery requires audio transducers of small physical size so as to not interfere with the operative field. There are many relatively inexpensive transducers in the commercial audio hifi market of appropriate size. Some produce suitable biological responses and tolerate long term use without failure. The authors describe factors to consider and methods used in testing such transducers.
