RESUMO
Breathing is silent in health but audible at a distance in chronic bronchitis and asthma. This clinical observation was tested by measurements of the intensity of the inspiratory breath sounds at the mouth at flow rates up to 60 1./min. There was a higher rate of increase in the intensity of the sound for equal increments in flow rate in these two diseases than in healthy subjects. Bronchodilator drugs reduced the intensity of abnormally loud inspiratory sounds.
