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.
A normal breath sound is similar to the sound of air. A doctor can hear normal breath sounds by placing the stethoscope on your chest, back, collarbone, and ribcage. A stethoscope can also pick up abnormal breathing sounds. These sounds are described as: 1  rhonchi (snoring sounds). 2  rales (clicking, rattling, bubbling).
