During auscultation, the stethoscope is placed on the patient's back at four locations, one of which is over the bronchial region. Bronchial lung sounds can be heard when the stethoscope is placed over these locations. These sounds are high-pitched, loud, and harsh, resembling the sound of air rushing through a tube. They are typically heard over the trachea and larger bronchi.
