“…The motivation to create permanent visual records of the distribution of sound energy in both frequency and time led to the first sound spectrograph, an analog electrical signal processing device, in the 1940s. 33 Its earliest application was in the presentation of vowel formants in speech, 34 and a decade later in the documentation of heart and lung sounds. 35 The display of lung sound waveforms in a time-expanded way shows details of both continuous and discontinuous adventitious sounds 6 but is most useful for the analysis of crackles.…”

This review summarizes our current understanding of mechanisms producing wheeze, its subjective perception and description, its objective measurement, and visualization, and its relevance in clinical practice.
