13. Significant differences in flow standardised breath sound spectra in patients with chronic obstructive pulmonary disease, stable asthma, and healthy lungs.
BACKGROUND--Spectral characteristics of breath sounds in asthma and chronic obstructive pulmonary disease (COPD) have not previously been compared, although the structural differences in these disorders might be reflected in breath sounds. METHODS--Flow standardised inspiratory breath sounds in patients with COPD (n = 17) and stable asthma (n = 10) with sign

14. Lung disease with chronic obstruction in opium smokers in Singapore: Clinical, electrocardiographic, radiological, functional, and pathological features
Fifty-four opium smokers with chronic obstructive lung disease were studied for two-and-a-half years. Forty-eight patients had a cough for at least two years before the onset of inappropriate exertional dyspnoea. Fine, bubbling adventitious sounds suggesting small airway disease were heard on auscultation over the middle and lower lobes in 38 patients.

15. Breath sounds in the clinical assessment of airflow obstruction.
In a group of 34 inpatients showing varying degrees of airflow obstruction we studied the relationship between breath sound intensity (BSI) and abnormalities of lung function. The BSI was evaluated by chest auscultation to provide a score, in a manner similar to that described by Pardee et al. (1976), and was found to correlate closely with indices of airflo

16. Diagnosis of asbestosis by a time expanded wave form analysis, auscultation and high resolution computed tomography: a comparative study.
BACKGROUND--Crackles are a prominent clinical feature of asbestosis and may be an early sign of the condition. Auscultation, however, is subjective and interexaminer disagreement is a problem. Computerised lung sound analysis can visualise, store, and analyse lung sounds and disagreement on the presence of crackles is minimal. High resolution computed tomogr

17. Potential for lung sound monitoring during bronchial provocation testing.
BACKGROUND--The use of lung sound monitoring during bronchial provocation testing has not been clearly demonstrated. The appearance of wheeze and changes in inspiratory breath sound intensity have been analysed and related to changes in spirometric parameters and to airways hyperresponsiveness. METHODS--Lung sounds were recorded in 38 patients undergoing a r

18. Accessory pathway for sound transfer in a neotropical frog.
A portion of the lateral body wall overlying the lung cavity of the arboreal frog, Eleutherodactylus coqui, vibrates in response to free-field sound. Peak displacement amplitude of the body wall in response to a natural call note presented at 73 decibels sound pressure level is 1.70 X 10(-9) m, roughly 8 decibels less than that of the ipsilateral eardrum, as

19. Characteristics of wheeze during histamine-induced airways obstruction in children with asthma.
BACKGROUND--An automated system has been developed for the detection of sound patterns suggestive of airways obstruction in long term recordings. The first step, presented here, was tracheal sound recording during histamine-induced airways obstruction. METHODS--The tracheal sounds of 29 children aged 8-19 years with asthma were recorded during airways obstru

20. Organic dust toxicity (pulmonary mycotoxicosis) associated with silo unloading.
An acute febrile illness associated with unloading silos occurs more frequently than any other farm associated respiratory illness in mid state New York. This report describes 29 cases of organic dust toxic syndrome (also known as pulmonary mycotoxicosis) occurring in 24 men and one woman with a mean age of 29 years. In 16 instances more than one worker was
