**7. Conclusion**

Constantly growing number of aged and senile people, increasing demands to the quality of life in modern conditions, as well as enhancing of audiological examination opportunities requires the necessity of searching the new approaches to the problem of age-related hearing impairment.

Presbycusis does not develop in all people. Genetic mechanisms are considered to be the crucial cause of age-related hearing loss development. Different diseases acquired throughout the lifetime and other factors can contribute to hearing loss progression in the case of hereditary predisposition to presbycusis.

Assessment of pathology level in the auditory system in patients with presbycusis is essential during the choice of further treatment and hearing rehabilitation. Therefore, it is necessary to use various audiologic methods during elderly people examination, including tests to evaluate the central auditory pathways. Elderly patients often suffer from impaired speech intelligibility, especially in background noise. This is one of the central auditory processing disorder symptoms. Currently, there are no data about significant achievements in development of drugs, improving speech intelligibility. According to research on brain neuroplasticity, specially designed auditory training programs have been shown to be able to refine speech signals' processing in central auditory pathways even in aged people. Auditory training designed with consideration of the individual features of auditory deficit should be included into rehabilitation programs of aged people with speech intelligibility disorders.
