摘要：

Pulmonary sounds were recorded before and after bronchodilator treatment in 20 patients with acute attacks of asthma. Analysis of the sounds showed that improvement in the forced expiratory volume in 1 s was associated with the following 2 changes in the sound signal: the proportion of the respiratory cycle occupied by wheeze was reduced from 86 to 31% on average and the sound frequency of the highest pitched wheeze was also reduced, from a mean of 440 Hz to 298 Hz.
