①Extraction of information from breath sounds
We are conducting research on a lung sound test system that can easily detect lung sounds at home and detect abnormalities at an early stage, such as a body fat meter or blood pressure monitor. We research a method to detect abnormal sounds from characteristics differences between abnormal sounds (called side noise) and normal lung sounds (using fluctuations in the frequency and energy of lung sounds).
Lung sounds of diseased persons including heart sounds (S1) and side noise
