Rales vs. Rhonchi: Know the Difference
By Shumaila Saeed || Published on January 16, 2024
Rales are crackling, rattling lung sounds indicating fluid in air spaces, while rhonchi are low-pitched, snore-like sounds, suggesting airway obstruction.
Key Differences
Rales, also known as crackles, are short, abrupt sounds heard primarily during inhalation. They suggest fluid in the small airways or alveoli. Rhonchi, in contrast, are continuous, low-pitched sounds resembling snoring, indicating larger airway obstructions.

The sound of rales is often compared to the noise of opening Velcro. This indicates conditions like pneumonia or heart failure. Rhonchi, meanwhile, sound like wheezing or snoring, often associated with conditions like bronchitis or COPD.

Rales are usually heard in the bases of the lungs and can change or clear with coughing or deep breathing. Rhonchi are typically heard in the bronchi and are less affected by coughing, suggesting more chronic obstruction.
