| Summary: | Very slow frequency sweep (5 minutes and 40 seconds per 1 octave) was adopted in ordinary Békésy audiometry as a new method for detailed measurement of hearing threshold along the frequency scale. The purpcse of this paper is to ascertain the limitation of this method in the viewpoint of exact recording of the threshold curve. One hundred and three ears with high tone loss of abrupt or dip type were tested. As the result, it was observed that the correct threshold was obtained in 101 ears, and only two ears showed so sharp slope of the threshold curve that the trace coincided the maximum limit of this recording. Accodingly, it was concluded that the usefullness of this method was recognized. |
