摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, particularly to otorhinolaryngology and audiology, and can be used in population survey, especially of young children, for detecting problems with hearing organs. Method for accelerated assessment of auditory function in patients (especially infants) involves recording of short-latent acoustical evoked potentials (SLAEP) with presentation of stimuli of different frequency and intensity, wherein SLAEP registration criterion is V peak imaging with minimum level of stimulus. Frequency-specific stimuli are located in different frequency intervals covering the whole investigated range of hearing, and their number is usually from 2 to 5. Stimuli are presented in the order defined by a sequence of maximum length (MLS) (for each frequency range) containing to cycles of duration of not less than 6 ms, where k equals 63, 127 or 255. Stimuli in each frequency sequence are presented simultaneously, and the corresponding sequences are shifted such that the distance between the stimuli for the neighboring frequency bands is not less than 2.5 ms, and for any other frequency bands of not less than 0.8 ms, then the recorded SLAEP signal is averaged over the entire length of the MLS and folded for all frequency intervals.EFFECT: method enables reducing the time of diagnosis, increasing the accuracy of detecting the presence and latency of the peaks and, as a result, improving reliability and accuracy of diagnosis.3 cl, 2 ex, 3 dwgИзобретение относится к медицине, в частности к оториноларингологии и сурдологии, и может быть использовано при обследовании населения, особенно детей раннего возраста, для выявления проблем с органами слуха. Способ ускоренной оценки слуховой функции у пациентов (особенно детей раннего возраста) включает регистрацию коротколатентных слуховых вызванных потенциалов (КСВП) при предъявлении стимулов различной частоты и интенсивности, при этом критерием регистрации КСВП является визуализация V пика при мини
