[Noise pathology in otorhinolaryngology].

Intensive industrial noise is an adequate stimulus of the hearing organ. Obviously, it can cause occupation-related hypoacusis in noise exposed workers. Pathological changes in other organs and systems that accompany cochlear neuritis are poorly studied; however, it seems that they have no noise-determined specific features.

[Indicators of the state of hearing and olfactory analyzers in healthy man].

This paper presents the concept of a biological norm, methods of experimental studies, and parameters of the hearing and olfactory function as derived from large-scale examinations of healthy people of different sex and age groups. On this basis parameters of the physiological norm for the hearing and olfactory function were calculated as applied to various age groups. The paper gives tables of average thresholds and limits of variations of hearing and olfactory sensitivity adapted for practical use.

[Clinical aspects of occupational pathology caused by noise and vibration].

The paper is concerned with the results of many year-old clinical studies on workers of vibration-risk and "noisy" professions. The authors consider occupational and biomedical risk factors contributing to the development of vibratory disorders and noisy cochlear neuritis, the main clinical syndromes of this occupational pathology, modern methods of their preclinical and early clinical diagnosis. The basic principles of differentiated follow-up and combined prevention as well as problems of therapy, medical labor examination and rehabilitation of patients with vibratory disease and occupational cochlear neuritis are described.
