The exercise is divided into two (2) sessions: daytime (7am - 10pm) and nighttime (10pm - 7am). The data obtained from this monitoring programme is compared with the guidelines issued bby the DOE.

The noise level meter is set at the A-weighted scale, and records noise level automatically at pre-set measurement interval. The recorded noise levels are automatically integrated by the built-in electronic system. The integrated noise descriptors in terms of Leq are then printed out.

The noise meter is calibrated acoustically by using a Larson Davis CAL 150.
