Частотні характеристики шумів, утворених горлянкою людини у нормі та при хворобі
Frequency characteristics of human pharynx hums in normal and diseased state

Summary/Abstract: The hums of a pharynx, which were originated in the attempt to make "a white noise", were explored in health and disease. To obtain the frequency spectrum the registered sounds were subjected to Fourier’s transformation. It has been shown that the noise spectrum was submitted by peaks reflecting the individual singularities of a human pharynx. On the average men have low-frequency 2−8 peaks, which is more than women (2-6 peaks of higher frequency). Diseases of the throat change peaks’ amplitude, alter its maximums (increasing or decreasing of frequency). It has been also observed the "spreading" of peaks on a spectrum or even complete depressing. The data argue for the possibility to identify a person by a spectrum of hums of the throat or to diagnose illness or process of convalescence objectively.
