Respiratory Sounds Compression
IEEE Transactions on Biomedical Engineering, 2008Recently, with the advances in digital signal processing, compression of biomedical signals has received great attention for telemedicine applications. In this paper, an adaptive transform coding-based method for compression of respiratory and swallowing sounds is proposed.

On the Blind Recovery of Cardiac and Respiratory Sounds
IEEE Journal of Biomedical and Health Informatics, 2015We present a method for smart auscultation by proposing a novel blind recovery of the original cardiac and respiratory sounds from a single observation mixture, in the framework of nonnegative matrix factorization (NMF). The method learns the basis spectra of the mixing sources in unsupervised or semisupervised fashion depending upon the applications ...

Adaptive Compression of Respiratory and Swallowing Sounds
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Compression of biomedical signals is of great interest in telemedicine applications for a fast and reliable online data transfer. In this paper, an adaptive method for compression of respiratory and swallowing sounds is proposed. The method is based on the transform coding of the signal and adaptively assigns two different bit allocations for encoding ...

Multi-channel Classification of Respiratory Sounds
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006In this study, respiratory sounds of pathological and healthy subjects were analyzed via frequency spectrum and AR model parameters with a view to construct a diagnostic aid based on auscultation. Each subject is represented by 14 channels of respiratory sound data of a single respiration cycle.

Respiratory Sounds: Laryngeal Origin Sounds
2018Laryngeal sounds reflect turbulence of air in the upper airway and are harsher and higher in pitch than normal lung sounds. A linear relationship between tracheal sounds and flow has been observed, and the frequency characteristics are associated with body height and length of the trachea in children.

PERSONALITY AND RESPIRATORY RESPONSES TO SOUND AND LIGHT
Psychophysiology, 1969ABSTRACTRespiratory amplitude (RA) and respiratory rate (RR) parameters were examined in student subjects (Ss) following stimulation with five intensities of sound and five intensities of light. All Ss completed the MMPI and were then divided into high and low ego strength (Es) groups on the basis of their scores on the Barron scale.

Asymmetry of respiratory sounds and thoracic transmission
Medical & Biological Engineering & Computing, 1997Breath sounds heard with a stethoscope over homologous sites of both lungs in healthy subjects are presumed to have similar characteristics. Passively transmitted sounds introduced at the mouth, however, are known to lateralise, with right-over-left dominance in power at the anterior upper chest. Both spontaneous breath sounds and passively transmitted

Detection of Respiratory Sounds at the External Ear
IEEE Transactions on Biomedical Engineering, 2004Several clinical and ambulatory settings necessitate respiratory monitoring without a mouthpiece or facemask. Several studies have demonstrated the utility of breathing sound measurements performed on the chest or neck to detect airflow. However, there are limitations to skin surface measurements, including susceptibility to external noise and ...

Time-scale segmentation of respiratory sounds
Technology and Health Care, 1998Respiratory sounds are composed of various events: normal and so-called adventitious sounds. These phenomena present a wide range of characteristics which make difficult their analysis with a single technique. Adapted time-frequency and time-scale techniques allow to fit best, under constraints, the accuracy of analysis of a time segmentation and, by ...
