During the drilling phase continuous noise monitoring will be carried out using a network of sound level monitors (SLMs) at several locations; one on the main site and at least three at remote locations called receptors.

The main site SLM will measure noise close to the drilling rig for source identification purposes. The remote locations are chosen to collect representative data for the surrounding area, paying particular attention to the closest sensitive receptors and population centres.

The system is configured so that GEL personnel are sent automated notifications should the noise levels at the site or any of the receptor locations approach or exceed prescribed levels.
