METHOD FOR ACOUSTIC DIAGNOSTIC focal lesions in human lungs

摘要

A method of acoustic diagnosis focal lesions in human lung comprising registration major respiratory sounds on the surface of the chest, the calculation of the spectra, the measurement of acoustic parameters characterizing respiratory sounds, mapping of acoustic parameters respiratory noise at the chest surface, comparing the acoustic parameters respiratory noise with a threshold that separates norm of pathology detection of local pathological sites, characterized in that the registration key respiratory noise filtered inspiratory mode "A" for the acoustic noise characteristics define the upper respiratory frequency -3dB cut-off spectrum and -20 dB from the maximum spectral amplitude, and for registering the main respiratory inhalation noise recorded during filtration in "A" mode, the acoustic respiratory noise characteristics define the upper cutoff frequency spectrum of the -3 dB and -20 dB from the maximum amplitude spectrum and local pathological sites diagnosed: ZPpri exceeding a cutoff frequency -3 dB threshold 443.6 and / or -20 dB cutoff frequency threshold 631.1, ZPpri exceeding a cutoff frequency -3 dB threshold 463.1 and / or -20 dB cutoff frequency threshold 713.1, ZPpri exceeding a cutoff frequency -3 dB threshold 451.4 and / or a cutoff frequency of -20 dB threshold 631, 1, the cutoff frequency is exceeded ZPpri -3 dB threshold 459.2 and / or -20 dB cutoff frequency threshold 650.6, ZPpri exceeding a cutoff frequency -3 dB threshold 428.0 and / or -20 dB cutoff frequency threshold 658.4, ZPpri exceeding a cutoff frequency -3 dB threshold 392.8 and / or -20 dB cutoff frequency threshold 664.3, ZPpri exceeding a cutoff frequency -3 dB threshold 396.7 and / or a cutoff frequency of 619.4 -20 dB threshold, is exceeded ZPpri -3 dB cutoff frequency
