an abnormal respiratory sound heard in auscultation and indicating some pathological condition. Rales are distinguished as dry or moist, according to the absence or presence of fluid in the air passages, and are classified according to their site of origin as bronchial, cavernous, laryngeal, pleural, tracheal and vesicular (crepitant).

amphoric rale
a coarse, musical and tinkling rale due to the splashing of fluid in a cavity connected with a bronchus.
atelectatic rale
a nonpathological rale which is dissipated by deep breathing or coughing. Such rales are frequently heard in those who breathe feebly and superficially, when on deep inspiration the moist walls of the unexpanded alveoli are suddenly forced apart by the entering air; after a few deep inspirations such rales become lost.
bubbling rale

cavernous rale

crepitant rale

dry rale
a rale produced by the presence of viscid secretion in the bronchial tubes, or by spastic contraction of the walls of the tubes; it has a whistling, musical or squeaking quality.
gurgling rale
a very coarse rale resembling the bursting of large bubbles; in pulmonary edema, heard over large cavities that contain fluid, and in the trachea in the 'death rattle'.
sibilant rale
a hissing sound resembling that produced by suddenly separating two oiled surfaces. It is produced by the presence of a viscid secretion in the bronchial tubes or by thickening of the walls of the tubes; heard in asthma and bronchitis.
