Airflow and Normal Lung Sounds
American Review of Respiratory Disease, 1988The relationship between total air flow and normal breath sounds recorded at 2 sites on the chest was investigated. Sounds were measured during rhythmic breathing, during flow rate tracking, and during flow rate tracking against an external resistance by subjects seated and in the left lateral decubitus position.

Quantification of heart sounds interference with lung sounds
Journal of Biomedical Engineering, 1989An index to quantify the contamination of lung sounds by heart sounds is described. Using the index, the efficacy of high pass filtering and adaptive filtering methods for the reduction of heart sounds is evaluated.

Steven Lehrer's introduction to auscultation is a primer of pulmonary diagnosis using lung sounds as its unifying theme. Intended to educate the ear as much as the mind, his kit is a self-contained learning experience for the medical student. It may also be useful for critical care and pulmonary service nurses.

Lung sound extraction from mixed lung and heart sounds FASTICA algorithm
2012 16th IEEE Mediterranean Electrotechnical Conference, 2012The reduction of interface by heart sounds in lung sounds, in order to improve the analysis of lung sounds has been discussed since the earliest work in 1986 [1] and numerous numbers of papers were developed further. In fact, a large amount of methods was proposed to quantify pure lung sounds, compared with heart sounds interference [2–5].

The American review of respiratory disease, 1984
A resurgence of interest in clinical auscultation is in progress. Recent technical advances permit more objective observations than were previously possible. Quantified lung sounds are being correlated with clinical, physiologic, and roentgenologic information.

Heart sound and lung sound separation algorithms: a review
Journal of Medical Engineering & Technology, 2016Breath and cardiac sounds are two major bio sound signals. In this, heart sounds are produced by movement of some body parts such as heart valve, leaflets and the blood flow through the vessels, whereas lung sounds generates due to the air in and out flow through airways during breathing cycle. These two signals are recorded from chest region.

“Can you auscultate this man’s lung?” A doctor points at you in the early morning ward round. What if this happens to you in your first clinical year? As you put your new stethoscope diaphragm to your patient’s chest, you might struggle to differentiate vesicular from bronchial breathing, stridor, wheezing, pleural friction rub, or crackles.

Heart sound cancellation from lung sound record using cyclostationarity
Medical Engineering & Physics, 2013From the mechanism of heart sound generation, it is known that heart sounds are cyclic following the frequency of the heartbeat. This paper proposes a short-time cyclic frequency spectrum to calculate the instantaneous cycle frequency (ICF) of heart sounds as an estimation of the frequency of the heartbeat.

How long has it been since you have heard bronchial breath sounds over the chest of a patient with pneumonia? How long since you have heard amphoric breath sounds, late inspiratory crackles, monophonic wheezes, inspiratory and expiratory squawks, and egobronchophony? Well, here is your chance to hear them.

A microcomputer based lung sounds analysis
Computer Methods and Programs in Biomedicine, 1993The use of a microcomputer in lung sound-analysis is described. The system was used experimentally in order to evaluate automated auscultation as a mean for improving the sensitivity of pulmonary health mass screening. The sound signals from four custom-made piezoelectric transducers, affixed at specific locations on the chest wall, and the breathing ...
