Instruments for Measuring Noise in the Workplace
Prevention of occupational risks related to noise

Noise measurements are difficult to perform, and numerous precautions must be taken, such as:

• the selection and quality of the sound level meter, microphones, digitization, and recording systems;

• calibration before and after the measurement;

• accounting for the influence of wind or drafts during outdoor measurements, as well as electric or magnetic fields, if applicable;

• fluctuations in the noise being measured, which determine the temporal and spatial sampling of measurement points and the duration of measurements;

• measurement uncertainties.

Accurate noise measurement is not possible without prior training of the operator.

Noise measurement and analysis devices are described in the articles
