Noise Monitoring Equipment

ERCD's noise monitoring equipment

Sound level meter


Although ERCD obtains the majority of its noise data via the London Heathrow, Gatwick and Stansted airports' Noise and Track Keeping (NTK) systems, it also has its own extensive range of professional noise monitoring equipment.

In addition to its precision Sound Level Meters, ERCD possesses several real-time Sound Level Analysers, capable of 1/3 octave band measurements.  These are often used in conjunction with professional DAT recorders, enabling ERCD to carry out detailed analysis of environmental noise back in the office.

On certain occasions unattended noise monitoring may be necessary, for example when measurements are required over long periods of time on a continuous basis.  In such cases ERCD also has several Noise Level Analysers, which are designed to measure environmental noise for several days without maintenance.

All ERCD test equipment currently in use is calibrated and traceable to UK National Standards.
