The SV 307A is the UK’s leading Class 1 noise monitoring station for long-term environmental use. Widely adopted for compliance and planning, it offers durability, precision, and autonomy. Its weatherproof housing ensures reliable operation in all conditions, protecting the advanced electronics inside. At its core is a next-gen MEMS microphone with a lifetime warranty, providing long-term accuracy. The patented dual remote check continuously validates performance, reducing maintenance. Trusted nationwide, the SV 307A delivers accurate, automated noise monitoring for construction, infrastructure, and urban environments.
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.
