a rapid series of short loud sounds (as might be heard with a stethoscope in some types of respiratory disorders); "the death rattle"

Noises, normal and abnormal, heard on auscultation over any part of the respiratory tract.

Abnormal rattling sound emanating from bronchi.

Noise produced by the air in passing through mucus, of which the lungs are unable to free themselves. This condition is chiefly observed at the approach of death, and is commonly called, "the ruttles." The term Rale has been given to different sounds during respiration, caused by the air in connection with fluid contained in the bronchi, or areolae of the pulmonary tissue; which are perceived by the stethoscope.

Any abnormal respiratory sound heard in auscultation. [See Table of Rales, pp. 382, 385]

A rattle: adventitious respiratory sounds which are heard on auscultation. They are always pathological. They are of two kinds: moist and dry, according as there is fluid in the air passages or not and are designated according as they are located in the larynx, trachea, larger or smaller bronchi; the air cells or the pleural cavity.
