To measure noise levels, the measuring device REED Instruments 9300 is used.
The sound level meter consists of a calibrated microphone, electronic circuits, and a display. The microphone measures small variations in air pressure associated with sound and converts them into electrical signals. These signals are then processed using the instrument’s electronic circuitry. The display shows the sound level in decibels.
The measuring device is calibrated according to ISO standards.
Unit of measurement – decibel (dB)
