ABSTRACT
The significance of asymmetric sensorineural hearing loss (ASNHL) is due to a special approach to diagnosis, followed by the process of hearing aids and auditory rehabilitation. Currently, there is no standard audiometric criterion for determining the forms of asymmetry, which significantly affects the assessment of the prevalence of ASNHL. The study aimed to assess the prevalence and classification of ASNHL forms in the older age group using two methods of calculation: 1) the difference in the average hearing threshold at speech frequencies (in the range of 0,5–4 kHz) ≥15 dB was detected in 14,14% of cases; 2) the different degree of hearing loss, according to the International classification, in the right and left ear was 35,98%. In most cases, asymmetry was manifested by bilateral sensorineural hearing loss of varying severity, prevailing in the group of long-livers – 82,6%. Given the potentially high prevalence of asymmetry depending on the audiological criterion, the results of the work are a reason for further research in the development of a unified method for verifying a clinically significant form of ASNHL.
