Method of classifying respiratory sounds

The Journal of the Acoustical Society of America, 1999
The invention provides a method of classifying respiratory sounds. The method provides the steps of selecting a first set of respiratory sounds and manually determining a classification content of the first set of respiratory events. The method further includes extrapolating the classification content of the first set of respiratory events to an at ...

Classifying Respiratory Sounds with Different Feature Sets

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
In this study, different feature sets are used in conjunction with (k-nearest neighbors) k-NN and artificial neural network (ANN) classifiers to address the classification problem of respiratory sound signals. A comparison is made between the performances of k-NN and ANN classifiers with different feature sets derived from respiratory sound data ...

Normal Versus Adventitious Respiratory Sounds

2018
Respiratory sounds are composed by normal and adventitious respiratory sounds which comprise the sounds heard over the trachea/mouth and chest wall. All sounds can be described using frequency, intensity, and timbre. Frequency and intensity are perceived by human beings as pitch and loudness, respectively.

Two-stage classification of respiratory sound patterns

Computers in Biology and Medicine, 2005
The classification problem of respiratory sound signals has been addressed by taking into account their cyclic nature, and a novel hierarchical decision fusion scheme based on the cooperation of classifiers has been developed. Respiratory signals from three different classes are partitioned into segments, which are later joined to form six different ...

Adaptive Compression of Respiratory and Swallowing Sounds

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

Method for respiratory sound analysis.

Medical instrumentation, 1978
A system is described for the analysis of respiratory sounds by means of a dual-channel sound envelope detector and a real-time spectrum analyzer. A three-dimensional spectral analyzer display for frequency, amplitude, and time has been utilized. Respiratory sounds have been observed with intensities up to 0.5 N/m2 and with normal frequencies in the ...
