Rales are described as which term?

Explanation:
Rales are crackling sounds heard on auscultation, produced when small airways or alveoli pop open around fluid or collapsed areas. They can be fine crackles (high-pitched, brief) or coarse crackles (louder, longer), and they typically indicate fluid in the lungs, such as pulmonary edema, pneumonia, or atelectasis. The other terms describe different sounds: wheezing is a musical, high-pitched sound from narrowed airways; stridor is a harsh, wheezy sound from upper airway obstruction; rubbing refers to a pleural friction rub from inflamed pleura.
