a. Noise Control Methods. The following general methods of noise control
may be applied in certain situations.
Reducing the amount of noise produced by the source.
Reducing the amount of noise transmitted through air or building
Revising operating procedures.
b. Examples of Noise Source Reduction.
Substituting new equipment for that now in use.
Periodically repairing and maintaining equipment.
Making changes in processing methods.
c. Examples of Reducing Noise Transmissions.
Increasing the distance between work areas and noise sources.
Providing acoustical barriers between work areas and sound sources.
Reducing reverberation by sound treating work area room surfaces.
Installing vibration mounts under equipment.
d. Examples of Operating Procedure Changes.
Providing acoustical observation booths.
Providing sound-isolated remote control positions.
Changing job schedules.
