Dredge noise control

Abstract

When dredges operate near residences, noise can be a concern. The major noise sources of a dredge can include diesel engines (casing and exhaust), generators, transformers, ventilation fans, electric motors, pumps, and winches. Some equipment is enclosed and some is on the open decks. Both airborne and structure-borne noise can be issues. As the dredge operates, its location and orientation relative to residences continuously change. Noise data and treatments are discussed from several dredging projects.
