Lung anomaly detection from respiratory sound database (sound signals)

Computers in Biology and Medicine, 2023
Chest or upper body auscultation has long been considered a useful part of the physical examination going back to the time of Hippocrates. However, it did not become a prevalent practice until the invention of the stethoscope by Rene Laennec in 1816, which made the practice suitable and hygienic. Pulmonary disease is a kind of sickness that affects the

Respiratory Sounds Compression

IEEE Transactions on Biomedical Engineering, 2008
Recently, 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.

Innovation in Analysis of Respiratory Sounds

Annals of Internal Medicine, 2016
It is difficult to describe the sounds of breathing, especially when different types of sound are present at the same time.

Respiratory sounds classification using statistical biomarker

2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017
In this paper, we have proposed a new feature extraction technique based on statistical morphology of lung sound signal (LS). This work attempts to (i) generate certain intrinsic mode functions (IMFs), (ii) select a set of informative IMFs and (iii) extract relevant features from the selected IMFs and residue.

Multi-channel Classification of Respiratory Sounds

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
In 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

2018
Laryngeal 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.

Time-scale segmentation of respiratory sounds

Technology and Health Care, 1998
Respiratory 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 ...

Snoring sound classification from respiratory signal

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Snoring is common in the general population and the irregularity could lead to the presence of Obstructive sleep apnea. Diagnosis of OSA could therefore be made by snoring sound analysis. However, there is still a shortage of robust methods to automatically detect snoring sounds without the need to calibrate for every individual. In this paper, a novel
