Crackles are the sounds you will hear in a lung field that has fluid in the small airways. As stated before, crackles and rales are the same thing, and this can often lead to confusion among health care providers. Crackles come in two flavours: fine and coarse. Fine crackles sound like salt heated on a frying pan or the sound of rolling your hair between your fingers next to your ear.

This lung sound is often a sign of adult respiratory distress syndrome, early congestive heart failure, asthma, and pulmonary oedema.
