Abstract
Ten volunteers, screened to exclude gross otological pathology, and 50 patients suffering from cochlear or vestibular disorder were studied. Auditory thresholds, determined both by Békésy audiometry and pure tone audiometry, were compared.
The results were as follows.
1) In many cases the auditory thresholds measured by Békésy audiometry were lower than those measured by pure tone audiometry.
2) The difference in auditory thresholds between Békésy audiometry and pure tone audiometry was ±10dB in 89-96% of the patients and volunteers.
3) The difference was large at 250, 4000 and 8000Hz in some cases.
