How does it work?

Noise Sentinel is a Web-based subscription monitoring service that has been specifically designed to enable industry to monitor and report compliance with environmental restrictions and to help manage impact.

Noise Sentinel provides environmental management capabilities to industry and local authority urban monitoring applications on a platform accessible from anywhere over the internet.

Noise Sentinel not only automatically reports compliance based on monitoring, it also monitors in real-time to enable operators to manage and avoid exceedances. With a clear and simple user interface optimised to manage measurements in real-time, Noise Sentinel can be easily used by operations staff. Thus, Noise Sentinel meets Best Available Techniques (BATs) of Industrial Pollution Prevention and Control (IPPC) legislation such as 2008/1/EC for industrial sites.

Managing noise exceedance

Noise Sentinel enables you to manage operations in order to maintain compliance with any noise, vibration, dust or air quality restrictions. In operation, Noise Sentinel’s real-time noise control application displays a map of the surrounding area with the monitoring locations identified. Current levels are shown on the map in real-time at each location. If the measured reach defined levels, warnings and alerts are triggered indicating either that set levels have exceeded defined criteria, or will breach the criteria if they continues at the current levels.

In addition, Noise Sentinel may be configured to send alerts by e-mail, SMS or to an external warning signal giving one or more additional notifications in the event of an alert. Alerts can be investigated, sound recordings listened to and the causes documented by operators. The information about the exceedance is recorded within Noise Sentinel and included in the regular Noise Sentinel reports.
