On this page we provide a description of several types of wheezes along with audio recordings.. High-pitched wheezing sounds are compared to a lower pitch wheezing sound using patient recordings and text.

Wheeze Sound

A wheezing sound has a musical quality. A wheeze might have a low or higher frequency sound. Higher frequency wheezes are similar to squeezing or whistling. A lower frequency wheeze can seem similar to snoring or gurgling. Low frequency wheezes are sometimes called rhonchi. Wheezes can occur during inspiration or expiration. A wheezing cough is another form of a wheezing sound.
