The protection of employees from occupational noise exposure is best achieved through implementation and maintenance of a comprehensive hearing conservation program (HCP). A major component of an HCP is the noise control phase, which provides the best long-term solution to in-plant noise problems. Many noise problems lend themselves to straightforward solutions. With an understanding of the principles of noise control and proper use of acoustical materials, it is feasible for industrial hygienists with a basic knowledge of the fundamentals of noise to develop noise control solutions; establish noise control priorities; and identify and select optimum products for retrofitting equipment.
