Description: 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. With some advanced education and training, it is feasible for industrial hygienists with a basic knowledge of the fundamentals of noise to develop noise control solutions; establish noise control priorities; identify and select optimum products for retrofitting equipment; work effectively with design engineers to implement a pro-active approach to noise control; predict the impact new equipment will have on the in-plant and community noise environment; and qualify new manufacturing or process equipment to determine whether it satisfies the stated noise criteria in the purchase specification. Several spreadsheet programs and significant references for noise control will be provided on CD to each participant, as well as demonstrated throughout the course.

Presenters: Dennis Driscoll, P.E., INCE Board Certified Noise Control Engineer, Associates in Acoustics Inc., Evergreen, CO
