Устройство для диагностики слухового аппарата на основе метода вызванных потенциалов

Abstract

The device relates to medical equipment in Otorhinolaryngology. Its function is to determine the threshold of sound perception and of a patient 's profound hearing loss. The method consists in the registration of evoked potentials stimulated by sound signals with various intensity and frequency. The device becomes portable and facile due to miniaturisation. The ability to process data with handheld mobile devices will eliminate the need of bulky PCs. The technical result of the method ensures an increase in the accuracy of the patient's threshold sensitivity determination at harmonic frequencies within the acoustic range of human perception. The method enables to reduce the total time of hearing loss diagnosis.
