Outdoor sound level monitoring stations certified PTB Class 1, traceable to IEC 61672-1:2013 — one 20–140 dB range that hears everything from a silence zone at 2 a.m. to a procession at full tilt. Geo-tagged, solar-backed and built for Indian weather, streaming live to dashboards, public display boards and the citizen app.
A network instrument has to survive alone on a mast for years — so the engineering is as much about weather, power and tampering as it is about acoustics.
RMS and peak across A, C and Z weightings, measured simultaneously; LAeq, LCPeak, LZPeak and band equivalents at 10-minute intervals; time histories down to 10 ms at 3+ frames per second — all on an AI-based dashboard with reporting and an alert engine, on web and mobile.
150+ Class 1 stations live across an Indian state for its pollution control board.
