If a rat dies near a steam pipe, the body wonât dry and the smell can be horrible for weeks. The odor from a dead mouse may last only a day or two. In fact, there may be no noticeable odor from a single dead mouse but several dead mice in the same area could smell for a few days.
Another source of crackling to look at, is the aluminum foil on the amps. This foil is supposed to shield RF and other extraneous noise. But most times all it does is cause unwanted noises. The foil does not make good contact with the chassis and will cause crackling that can come and go. Loose components can also cause some crackling or even the signal dropping out. Some components to look at are pots, jacks, transformers and mechanically connected grounds.
Possible Causes of Neck Cracking. Crepitus, sometimes called crepitation or cavitation, refers to any type of noise or sensation such as a cracking, popping, snapping, or grinding sound that is heard during neck movement. For example, feeling a cracking sensation in the neck when turning the head to back up the car. See Neck Strain: Causes and Remedies Crepitus can occur in any moveable joint in the body, and there are many moveable joints in the neck. The neck joints are bathed in an oily-like substance call synovial fluid, which allows motion to freely occur in between the bones. The underlying cause of crepitus in the neck is still not yet fully understood.
