HIGHWAY CONSTRUCTION EQUIPMENT NOISE HAZARDS

CONSTRUCTION EQUIPMENT The principles of noise control are well understood and can be employed to reduce noise of construction operations. The pulsations in atmospheric pressure that the ear perceives as noise may originate with an aerodynamic disturbance such as the turbu­ lence produced by the engine cooling fan.
