A method of computerized cough sound analysis is described. The sounds of nocturnal and post-exercise coughs from a child with asthma were compared with those from a child without asthma. The spectrographic patterns of voluntary cough at rest from the two children were similar. The pattern seen after exercise from the asthmatic child was different from the resting cough but similar to that seen during recorded nocturnal cough. In contrast the post-exercise cough from the non-asthmatic child was similar to the cough seen at rest. Refinement of this method of cough sound analysis may be useful in the diagnosis of asthma in young children.
本文描述了一种计算机化咳嗽声音分析方法。对一名哮喘儿童夜间和运动后咳嗽的声音与一名非哮喘儿童的咳嗽声音进行了比较。两名儿童静息时自主咳嗽的频谱图相似。哮喘儿童运动后的咳嗽模式与静息咳嗽不同，但与记录的夜间咳嗽时的模式相似。相比之下，非哮喘儿童运动后的咳嗽与静息时的咳嗽相似。改进这种咳嗽声音分析方法可能有助于幼儿哮喘的诊断。
