The results of phase angle estimations in 62 middle ears in healthy peoples were presented. Examinations were performed using multifrequency middle ear analyser with probe tone frequency from 250 to 2000 Hz. Own laboratory norms were estimated for the peak value and phase angle value in resonance frequency of middle ears. Obtained results were compared with other authors examinations. No significant statistical corellations between peak value of phase angles and probe tone frequency of impedancemeter were found.
