Definition
Noun (Medical term): A rattling or whistling respiratory sound, often likened to snoring or wheezing, that is heard through a stethoscope during expiration. It is caused by air passing through obstructed or fluid-filled airways.
Usage
This term is used almost exclusively in medical contexts to describe an abnormal lung sound heard during a physical examination. * The doctor detected a rhonchus in the patient's lower left lobe, suggesting a possible mucus plug. * The presence of bilateral rhonchi indicated widespread airway inflammation.
Advanced Usage
- The plural form is rhonchi (/ˈrɒŋkaɪ/).
- Rhonchi are typically classified as continuous adventitious lung sounds, differentiating them from discontinuous sounds like crackles.
- They are often described as low-pitched, sonorous (deep and snoring-like), or sibilant (higher-pitched and whistling).
Variants and Related Words

- Wheeze (noun/verb): A related but distinct high-pitched whistling sound, often heard during both inspiration and expiration, typically associated with narrowed airways (e.g., in asthma). Rhonchi are generally lower-pitched.
