An automatic method for crackle detection is developed, based on analysing the spectral stationarity of the lung sound. The method is validated by studying the crackles of 20 adult patients; 10 with fibrosing alveolitis (FA) and 10 with bronchiectasis (BE). The number of crackles detected by ...
discontinuous s's adventitious sounds that last less than 0.2 sec and come in a series; the most common kind are rales (crackles). ejection s's high-pitched clicking sounds heard in septal defects just after the first heart sound, attributed to sudden distention of a dilated pulmonary artery...
Abnormal lung sounds heard when listening to the chest as the person breathes. These may be wheezes, crackles (rales), or stridor. They do not include sounds produced by muscular activity in the chest wall or friction of the stethoscope on the chest. adventitious lung sounds adventitious lung...
context information of lung sounds over time, obtaining an accuracy of 99% in recognizing COPD patients. In addition, Altan et al. [27] proposed a deep belief network-based model combined with a three-dimensional (3D)-second order difference plot of lung sound signals to distinguish the severi...

These are normal sounds and abnormal sounds including wheezes, coarse crackles, fine crackles, and rhonchi (Mikami et al., 1987). The abnormal sounds can be signs of lung diseases, such as pneumonia, emphysema, chronic obstructive pulmonary disease (COPD), and asthma. The traditional chest ...

The frequency spectrum of crackles varies between 200 and 2000 Hz range while their duration is usually less than 20 ms. In most of the pulmonary diseases, the severity of the disease has a strong correlation with the number of crackles per breath. Moreover, different lung diseases can be ...
