Noise monitoring stations

A noise monitoring station is an outdoor, usually unattended, system built around a class 1 sound level meter with a weather-protected microphone, a power supply for days or months of autonomy and a data link to a server or cloud platform. The meter inside is specified to IEC 61672-1; the station as a whole is specified by its autonomy, protection rating, connectivity and remote-control software. The table lists every station and outdoor kit in the database.
