What is a noise monitor?

In the UK, a noise monitor is a precision tool for continuous environmental sound monitoring in line with ISO 1996-2:2017 and BS 4142. It tracks A-weighted levels, frequency spectra, and key meteorological data such as wind, rain, and humidity. To meet regulations, it must deliver Class 1 accuracy, measure low frequencies, support system checks, include GPS synchronisation, and log noise events. The SV 307A meets all these criteria, making it the preferred solution for environmental noise monitoring across the UK.
