A sound level meter is used for acoustic measurements.
It is commonly a hand-held instrument with a microphone.
The diaphragm of the microphone responds to changes in air pressure caused by sound waves.
That is why the instrument is sometimes referred to as a Sound Pressure Level Meter.

The decibel is a unit of measurement used to express the ratio of one value of a power or field quantity to another on a logarithmic scale, the logarithmic quantity being called the power level or field level, respectively.
