Tussiphonographic examinations were conducted in 21 probands admitted to hospital with chronic bronchitis, diagnosed by spirometry. Voluntary cough registered in subjects with obstructive chronic bronchitis appeared in the recordings as a marked multifarious sound, an increased mono-sound or a connected double-sound. The average value of cough sound intensity was increased to 244%, and the duration of cough was delayed to 77% when compared to normal values. No correlation was found between the changes observed in spirometric values, and values indicated by the tussiphonogram.
