Noise is measured in A. Watt B. REM C. Centigrade D. Decibel

The correct answer is D. Decibel.

A decibel (dB) is a logarithmic unit that expresses the ratio of a physical quantity (such as sound pressure, power, voltage, etc.) to a reference value. It is often used to

express the level of a sound, with 0 dB being the threshold of human hearing.

A watt (W) is a unit of power, which is the rate at which energy is transferred or converted.

A REM is a unit of measurement of the depth of sleep.

Centigrade is a scale of temperature that is based on the freezing and boiling points of water.
