Our Noise Pollution Section lists, in some detail, the wide range of instruments we hire for all environmental noise monitoring surveys. This page is designed for customers who want to hire equipment that others are using and meets the following requirements

Environmental Noise Measurement of Leq, Lmax, Lmin etc., + statistics.
Environmental Noise + Measurement of 1/1 & 1/3 octave levels and statistics, as well.

All our meters, and calibrators are delivered with certificates traceable to UKAS.

It is good practice to use a calibrator on-site before and after each measurement and log the fact with all serial numbers in the report.
