Békésy Test
Békésy is a type of automatic audiometry. It is diagnostically important from the classification of the
results into one of the five types (after Jerger, et al) when responses to continuous and pulsed tones are
compared. The Békésy test is a fixed frequency test. Pure tone or narrow band noise can be selected. As
a standard a continuous tone is selected for the Békésy test, if pulsing tones are preferred this can be
changed by pressing “Settings” (19) and changing continuous to pulse.
Please refer to the HW Test section above for key function descriptions for Function Keys (10),
(11), (12), (16), (17).
