Normal Lung Sounds. Normal breath sounds are classified as tracheal, bronchial, and vesicular sounds. The patterns of normal breath sounds are created by the effect of body structures on air moving through airway. Normal lung sounds can be considered abnormal when the sound occurs in an area in which the sounds should not be present.
Normal findings on auscultation include: 1  Loud, high-pitched bronchial breath sounds over the trachea. 2  Medium pitched bronchovesicular sounds over the mainstream bronchi, between the scapulae, and below the clavicles. 3  Soft, breezy, low-pitched vesicular breath sounds over most of the peripheral lung fields.
