Makarenkova A.A., Oliynik V.N., Nabiev R. «On automatic detecting of the inspiration/expiration phases of respiratory cycle by time-frequency spectral properties of breath sounds» КОНСОНАНС-2013. Акустический симпозиум (1–2 октября 2013 г.), с. 194-199 (2013)

A technique for automatic detection of inspiration, expiration and respiratory pause is algorithmically implemented by tracing of intervals corresponding to the minima of the respiratory sound acoustic intensity in frequency band typical for a vesicular breathing. An approbation of the method on respiratory signals corresponding to the different types of breathing and receiving devices confirms high effectiveness of the proposed approach.
