Examples of Engineering Controls
The diagram shows how installing softer bends in the pipe and increasing the distance between the valves will reduce the turbulence in the line and, consequently, reduce the noise generated.
Changing a hard bend to a soft bend in a steam line to reduce noise levels.
Often, large pressure drops across valves, which cause noise, can be prevented with in-line diffuser silencers, which reduce the pressure upstream of the valve. Installing a muffler on the end of the nozzle is another option. All these methods can help reduce noise from compressed air sources.
Common examples of the implementation of such controls are:
- Installing a muffler
- Erecting acoustical enclosures and barriers
- Installing sound-absorbing material
- Installing vibration mounts and providing proper lubrication
