The lower airways of asymptomatic chronic obstructive pulmonary disease (COPD) patients can be colonized by bacteria, mainly Haemophilus influenza, Streptococcus pneumoniae, and Moraxella…
Acoustic analysis of snoring sound in patients with simple snoring and obstructive sleep apnoea.
Significant differences in the sound power spectrum of snoring sound between subjects with simple snoring and obstructive sleep apnoea patients are demonstrated.

Sensitivities between 100% and 71%, as a function of flow level related to wheezing segments detection, were achieved, and limited bandwidth parameters, which measure the bronchodilator response, were studied.
Automatic Differentiation of Normal and Continuous Adventitious Respiratory Sounds Using Ensemble Empirical Mode Decomposition and Instantaneous Frequency
