PDC 413
Noise Control Engineering - SOLD OUT

intermediate | 1.34 CM Points/ 8 Contact Hours/ 1.0 CEU/COC Point | Sunday | 8:00 a.m. - 5:00 p.m. | Limit: 45



The most effective way to prevent occupational noise-induced hearing loss is through effective implementation of engineering noise controls. With some advanced education and training, it is feasible for IHs 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; and predict the impact new equipment will on the existing noise levels.

Value Added:
Receive a copy of The Noise Manual and a CD containing spreadsheet programs and references.

Familiarity with the fundamentals of noise and basic terminology: A-weighted sound levels, decibel addition, octaveband frequencies, noise dose, and employee time-weighted average noise exposure. 

Upon completion, the participant will be able to:

  • Conduct a noise-control survey.
  • Identify noise-generating mechanisms and prioritize items for their control.
  • Develop feasible engineering controls through effective implementation of the principles of noise control.
  • Discuss noise-control design and retrofit applications for a variety of industrial equipment.
  • Work effectively with design contractors, acoustical product suppliers, and consultants to achieve stated noise criteria or goals.
