The sound produced by the passage of air through mucus accumulated in the larger bronchi or trachea, or through softened tubercular matter. This rale occurs in catarrh, and in softened tubercle. When carried to a very high degree, it constitutes gurgling, (F.) Gorgouillement. The subcrepitant rhonchus, (F.) Rale sous-crepitant, is produced by the bubbling of air through liquid of variable consistence in the minute bronchial tubes. When beard at the base of both lungs, it is a sign of capillary bronchitis. When heard at one base only, it is generally connected with tuberculosis higher up.
