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.
#3 Cause of crackling while you breathe: Bronchitis. Bronchitis is where the bronchial tubes in your lungs become irritated and inflamed. There are two types of bronchitis: acute or chronic. You can get acute bronchitis when you have an underlying infection causing it. This results in wheezing and often a crackling sound while breathing.
