Equipment for environmental noise measurements
The equipment for environmental noise measurements is a measuring chain of several devices connected in a system that includes a microphone, a modular precision sound analyzer, an anemometer, and a humidity and temperature meter. It is intended for measuring the level of environmental noise. Measurements are carried out in accordance with the SIST ISO 1996-2 standard. The modular precision sound analyzer records the level caused by the source in a selected time interval via a microphone that is placed next to the noise source in question. In the analysis, the dynamics of the source are also taken into account, since according to the legislation, the load of most sources must be calculated on an annual average. Since the weather conditions at the time of noise measurements can significantly affect the measurement results, especially at greater distances from the source, they must be properly evaluated and taken into account when evaluating the results.
