Evoked Otoacoustic Emissions (EOAEs) are studied by the use of the recently built EOAEs processor. For this purpose 101 dentist students underwent screening earphone audiometry and electrostimulation high-rrequency tests and were tested with use of the EOAEs processor. Three different parameters were evaluated from the recorded waveforms. Great inter- and intraindividual differences within the recordings were observed. The problems concerning the probe fitting are also discussed.
