Bronchial breath sounds

Bronchial breath sounds are characterised by expiration and inspiration producing noise of equal loudness and duration, sounding like blowing through a hollow tube. The expiratory sound is heard during the greater part of expiration, whereas the inspiratory sound stops abruptly at the height of inspiration, with a pause before the sound of expiration is heard.
