![]() FAST mode (125 ms) and SLOW mode (1 second), software configurable.Sound pressure level measurement (no weighting filter).New Sound Level Sensor to control Noise Pollution Leq is often described as the average noise level during a noise measurement and it is the magnitude used for many regulations of noise control at work places and the street. The value given is the LeqA (Equivalent continuous sound level, with A weighting) that allows to calculate the average sound pressure level during a period of time. Specifically with an accuracy of ☐.5 dBA (1KHz) similar to the Class 2 type devices. The new Noise / Sound Level Sensor for Plug & Sense! has been designed following the specifications of the IEC 61672 standard for sound meters. The report explains how harmful for health is traffic noise that is currently affecting one in five Westerners that are regularly exposed to sound levels at night. In fact, the World Health Organization (WHO) has stated that noise pollution is the second cause of illness for environmental reasons, after air pollution.
