These are tiny sacs of air and inflate and deflate with each breath. This usually occurs in the smaller parts of the lungs, like the alveoli. These sounds are formed when air moves into closed spaces. The terms rales or crackles have been used interchangeably and are usually a matter of preference, not a difference in the condition. Rales are a higher-pitched sound sometimes called crackles or bibasilar crackles. Listen to rhonchi here on the Medzcool YouTube channel.

This low-pitched sound that usually starts in the larger airways in the lungs. The difference between the two is in the pitch and the exact cause of the sound. Rales and rhonchi can both be coarse, even crackling sounds.
