Engineering Controls
Changes at the Source and Path
Engineering control strategies also include making physical changes at the noise source or along the transmission path that reduces the noise level at the employee's ear.
Engineering controls involve changes at the noise source or transmission path.
Typical engineering controls involve:
- Install sound barriers or acoustic partitions: These can be used to block or absorb noise, and can be made from materials such as concrete, brick, or acoustic panels. (see image)
- Use vibration isolation systems: These can be used to reduce the transmission of noise and vibration from equipment to the surrounding environment. Examples include shock absorbers and vibration-damping pads. (see image)
- Modify the workspace layout: This can involve repositioning noisy equipment or workstations to reduce the impact of noise on workers. For example, placing noisy equipment in a separate room or enclosure.
- Implement noise-reducing materials: This can include installing acoustic ceiling tiles, carpeting, or curtains that absorb sound.
