Abstract

Auscultation of breathing sounds is a common practice since the antiquity. In 1819, it was incorporated into medicine after the publishing of Laennec's work. Laennec invented the stethoscope and related the heard sounds to several breathing pathologies. McKusick et al. (1950) developed the first electronic equipment that records and analyzes physiological sounds [4], being followed by other researchers [5]. Recently, a task force of the European Respiratory Society established guidelines for computerized respiratory sound analysis [3].
