Abstract
To improve the proper diagnosis rate beyond that of sweep-frequency tympanometry for auditory ossicle examination, a new method adopting a stepwise-variable-frequency and a wide-band frequency of probe tones is proposed to be used in place of the conventional method. It is shown that there are similar trends in the measured properties when the proposed method is applied to an artificial model with the external auditory meatus, tympanum, and auditory ossicles and to a subject. There are differences in examinational indexes of the auditory ossicles when the method is applied to the artificial model with and without a push-spring for the disarticulation of auditory ossicles. The results indicate that the proposed method is promising.
