Problems solved by technology

[0002] Pulmonary auscultation sounds are related to the pathological conditions of the lungs. However, due to the different hearing sensitivities of the human ear in different frequency bands, and the moist rales in auscultation sounds have low intensity, short duration and wide bandwidth, different doctors based on auscultation Inconsistencies in the diagnostic results obtained are frequent

Abstract

The invention discloses a lung sound signal processing method, a processing device and a computer readable storage medium. The lung sound signal processing method comprises steps: lung sound signals are acquired; an empirical mode decomposition algorithm is adopted to decompose the lung sound signals, and a moist rale component and a respiratory sound component are calculated and obtained; based on the respiratory sound component, an inspiratory phase time period is acquired; moist rale signals located in the inspiratory phase time period are extracted from the moist rale component; and basedon the moist rale signals, at least one feature parameter is acquired.

Description

technical field [0001] Embodiments of the present disclosure relate to a lung sound signal processing method, a processing device, and a readable storage medium. Background technique [0002] Pulmonary auscultation sounds are related to the pathological conditions of the lungs. However, due to the different hearing sensitivities of the human ear in different frequency bands, and the moist rales in auscultation sounds have low intensity, short duration and wide bandwidth, different doctors based on auscultation Inconsistencies in the diagnostic results obtained frequently occur. Using digital auscultation for auxiliary diagnosis of lung disease can make up for the subjectivity and limitations of doctor's auscultation. Contents of the invention [0003] At least one embodiment of the present disclosure provides a lung sound signal processing method, including: acquiring the lung sound signal; using the empirical mode decomposition algorithm to decompose the lung sound signa...
