For many decades, the physical mechanism that causes the cracking sound as a result of bending, twisting, or compressing joints was uncertain. Suggested causes included: Cavitation within the joint—small cavities of partial vacuum form in the synovial fluid and then rapidly collapse, producing a sharp sound. [7] [8] Rapid stretching of ...
Snapping scapula syndrome, also known as scapulocostal syndrome or scapulothoracic syndrome, is described by a "grating, grinding, popping or snapping sensation of the scapula onto the back side of the ribs or thoracic area of the spine" (Hauser).

Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
This reduces noise in problem areas although trains make a distinctive tonal sound on freshly-ground track due to the pattern on the rail left by the grinding process, which wears flat over time. Rail squeal is a sound caused by a train's wheels slipping under specific conditions, usually around sharp curves. [4]
Noise 1: This is a very distinct noise that is usually much louder than the second noise that can be associated with this transmission. If the vehicle is not making any noise when trying to verify the condition, it can be induced by making several tight left hand circles with the vehicle at normal operating temperature.
The 53-year-old man from Macon driving the 2000 Ford Econoline van reported he was traveling about 50 mph when the front end began shaking, followed by a loud noise, then a grinding sound. He was ...
