ABSTRACT
There has been a steady increase in the prevalence of hearing loss among people in many countries around the world. One of the main reasons for this negative trend is an increase in life expectancy and an increase in the proportion of the elderly people, which means an increase in the number of people with age-related changes in the auditory system (presbycusis). Aging is accompanied primarily by damage to the structures of the inner ear, but it can also affect the central parts of the auditory analyzer, causing frustration at all levels of the auditory neural pathway. Presbycusis is accompanied by impaired hearing and speech intelligibility. Along with speech hearing, spatial hearing suffers. Just as in other countries of the world, in Russia the prevalence of age-related hearing loss is increasing year by year. The data on the prevalence of hearing impairment in the Russian Federation vary, due to the lack of uniform approaches to the registration of persons with hearing impairment. Creation of a surdologic register is necessary for information support of complex medical and social rehabilitation of surdological patients. Since hearing loss has a significant negative impact on the quality of life of patients, knowledge of the prevalence of hearing disorders among the population will allow to plan properly the need for technical means of hearing and speech rehabilitation at the state level, to promote social rehabilitation and active longevity of citizens of older age groups.
