The most reliable and effective method of reducing employee noise exposure is through the design and implementation of engineering noise controls. Effective noise controls often include modification, retrofit, or replacement of noise-producing equipment, but may also include the introduction of barriers or enclosures, or administrative controls, such as modification of work schedules.
The Associates In Acoustics approach to engineering noise controls is to start with the source. Skillful measurement of sound and vibration coupled with thorough observation of the equipment give us an understanding of the noise-producing mechanism at a fundamental level. We are then able to work with the client to determine the most feasible and effective noise mitigation that is specific to the source.
In most cases, a retrofit of the machine with a standard or custom-fabricated noise-control part will achieve the desired results. An effective and practicable retrofit of the noise source is usually the most desirable strategy. When source modification or retrofit is infeasible and replacement is impractical or uneconomical, the solution may be through interruption of the sound transmission path with a barrier or enclosure. The final option is to reduce employee exposure through strategic equipment relocation or modification of schedules.
AIA has provided industrial noise control engineering services since its inception and serving clients in the industrial and manufacturing sectors continues to be our primary focus.
