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.
breath sounds. can be heard with a stethoscope on the chest and trachea. The normal sounds are the normally very faint vesicular murmur and the louder, tubular sounding bronchial tones. They are made by the air passing through the tubes of the bronchi. Adventitious (abnormal) sounds are the rale, rhonchus, grunt, friction rub, laryngeal stertor, wheeze and peristaltic sounds.
