As with any occupational hazard, control technology should aim at reducing noise to acceptable
levels by action on the work environment. Such action involves the implementation of any
measure that will reduce noise being generated, and/or will reduce the noise transmission
through the air or through the structure of the workplace. Such measures include modifications
of the machinery, the workplace operations, and the layout of the workroom. In fact, the best
approach for noise hazard control in the work environment, is to eliminate or reduce the hazard
at its source of generation, either by direct action on the source or by its confinement
