Engine knocking. In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside ...
A refrigerator death is death by suffocation in a refrigerator or other air-tight appliance. Because, by design, such appliances are air-tight when closed, a person entrapped inside will have a low supply of oxygen.

In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy.
