ROAD CONSTRUCTION NOISE PREDICTION AND MEASUREMENT - A CASE STUDY.

Noise predictions and measurements have been made during the earthworks phase of a road construction scheme to illustrate the roles that noise prediction and measurement can play in assessing noise control strategies in earthworks operations. Measurements over periods of six hours or more showed that levels at the site boundary ranged from 70 to 83 dB(A) and at 30 m from the boundary ranged from 62 to 75 dB(A). It is suggested that, in practice, where details are not known accurately before the start of operations, the prediction method can be used to identify noise sensitive areas where noise control may be needed and to determine appropriate noise monitoring strategies to be carried out during the construction work.
