Bronchial sounds are a type of lung sound that can be heard during breathing. They are produced when air moves through the large airways, specifically the bronchi. These sounds are typically loud and high-pitched, resembling a hollow or tubular quality. In a clinical setting, healthcare providers listen for bronchial sounds using a stethoscope. Normal bronchial sounds are usually heard over the trachea and may indicate healthy airflow. However, if these sounds are heard in other areas of the lungs, it may suggest an underlying condition, such as pneumonia or lung consolidation.
