[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. The tabulated data can be employed to evaluate examination results, to make early diagnosis, and to assess performance capabilities in the norm and pathology.
