[Outfit for impedance studies of the auditory function].
An apparatus for measuring the middle-ear impedance enabling it to record the threshold of the acoustic reflex and to measure its dynamic characteristics with contralateral and ipsilateral stimulation, as well as to carry out tympanometry of the middle ear and to judge on the ventilation function of the auditory tube is described. The set-up includes: a device for pressure feeding and recording in the external ear, an arrangement for imparting a sonic stimulus and the one for input and recording the air pressure.
