An adventitious lung sound heard on auscultation of the chest, produced by air passing over retained airway secretions or the sudden opening of collapsed airways. It may be heard on inspiration or expiration. A crackle is a discontinuous adventitious lung sound as opposed to a wheeze, which is continuous. Crackles are described as fine or coarse.
