Pleural rub is described as which of the following?

Pleural rub is a friction sound produced when inflamed pleural surfaces rub against each other during breathing. The sound is rough and grating, like a scratchy creak, and is best heard with a stethoscope as the patient breathes in and out. This finding points to pleuritis, since it arises from the friction of the two pleural layers coming together inflammation causes. It differs from pneumonia, which is an infection of the lung tissue and usually presents with crackles or other lung sounds rather than a pleural friction rub. It’s also not the sound produced by air moving through secretions in the airways. So the described grating sound captured during respiration is the pleural rub.
