Clinical Efficiency of the LOT-Békésy Test

Clinical Efficiency of the LOT-Békésy Test Abstract The fixed frequency Békésy tracing was found to be an efficient screening device for detecting the presence of nonorganic hearing loss when the off-time of the pulsed signal was lengthened from 200 to 800 msec. The lengthened off-time (LOT) test was given to 340 hearing-impaired patients in a clinic population with a high incidence of nonorganic hearing loss. The LOT test correctly identified 99.6% of the organically-impaired patients and 95.5% of the nonorganic patients for an overall efficiency of 98.3%. References 1.

Abstract

Abstract The fixed frequency Békésy tracing was found to be an efficient screening device for detecting the presence of nonorganic hearing loss when the off-time of the pulsed signal was lengthened from 200 to 800 msec. The lengthened off-time (LOT) test was given to 340 hearing-impaired patients in a clinic population with a high incidence of nonorganic hearing loss. The LOT test correctly identified 99.6% of the organically-impaired patients and 95.5% of the nonorganic patients for an overall efficiency of 98.3%. References 1.
