Crepitation or Crackles
Crepitation also known as crepitus is the sound heard when the ends of a broken bone move together.
Crepitate is a verb which means to make a crackling or grating sound; to crackle. Example sentence:He changed his mind about retrieving his hat when he heard the ice crepitate under his feet.

Cellular emphysema, or in certain bone fractures
Both crackles and crepitation are abnormal breath sounds heard during auscultation. Crackles are discontinuous, brief, popping sounds usually heard during inspiration, indicative of fluid in the lungs. Crepitation is a coarse, crackling sensation often felt when rubbing bone ends together, frequently occurring in joints affected by arthritis.
One possible cause is pulmonary congestion from left ventricular failure. See links for more.
Patellofemoral crepitations is noise and/or vibration that is felt when the person bends and straightens the knee. It is a symptom of several conditions, one of which is a weakness of the kneww muscles which require exercise in the form of walking or physical therapy.patell = platella or knee capfemor = femur or thigh-al = pertaining to (adjective ending)crepitation = to crackle, crack, creak
Yes, grasshoppers produce sounds to attract mates and protect their territory. Unlike crickets, grasshoppers do not make sound by rubbing their wings together. They make sound using stridulation or crepitation. Stridulation is rubbing one body part against another, crepitation is when the grasshoppers snap their hindwings rapidly as they fly.
MI causes heart failure. . in heart failure , the increase of left ventricular pressure with failure of blood to pump into aorta occurs. . leads to back flow of blood into lungs through pulmonary veins. . this results to interstitial pulmonary odema and opening of alveoli , during inspiration is not normal, with external pressure to its normal opening. . this takes place with a sound , called fine crepitations
Grasshoppers make sounds in one of two ways - stridulation or crepitation. Stridulation involves rubbing one body part, which acts as a rasp, against another, which acts as a scraper. Most grasshoppers stridulate to make their characteristic sounds. In grasshoppers, a row of pegs along the inside of the hind leg acts as a file, or rasp. The grasshopper rubs this leg surface against the thickened forewing, causing a vibration and thus a sound. A few grasshoppers, most notably some band-winged grasshoppers in the family Oedipodinae, use an entirely different method of sound production, called crepitation. These grasshoppers snap their hindwings rapidly as they fly, making a distinct crackling sound.
Arthritis. Bones are normal separated by a cushioning on their ends called cartilage, which is the substance that allows bones to glide gently over one another (such as the knee or elbow joint, and this meeting of two bones is called an "articulation"), when this cartilage is lost the bones come into contact with each other this is known as arthritis.
