ABSTRACT:
A pair of probes insertable into both auditory canals of a patient are provided, each probe carrying a readily replaceable, inflatable bladder for sealingly positioning the probes. A trio of conduits terminate at a disc at an end of each probe to provide audio stimulus, audio detection and air pressure control. Transducers coupled to sound transmitting conduits are carried in a pair of housings mounted on a frame which supports the axially and radially adjustable probes.
