The sound can be created when two rough surfaces in the human body come into contact - for example, in [[osteoarthritis]] when the [[cartilage]] around joints has eroded away and the joint ends grind against one another, or when the [[fracture]] surfaces of two broken [[bones]] rub together. In soft tissues, crepitus can be produced when gas is introduced into an area where it normally isn't present. The term can also be used when describing the sounds produced by [[lung]] conditions such [[as]] [[interstitial lung disease]]—these are also referred to as "[[rales]]". Crepitus is often loud enough to be heard by the [[human ear]], although a [[stethoscope]] may be needed to detect instances caused by [[respiratory]] diseases. In times of poor surgical practice, post-surgical complications involved [[anaerobic]] infection by ''[[Clostridium perfringens]]'' [[strains]], which can cause [[gas gangrene]] in [[Tissue (biology)|tissues]], also giving rise to crepitus. Subcutaneous crepitus is a crackling sound resulting from [[subcutaneous emphysema]], or air trapped in the [[subcutaneous tissue]]s.
