Abstract: Noisy pressure reducing stations are a headache. But noise is a problem only when someone hears it if there are no people within ten miles of a noisy regulator, there is no problem. The solution is easy! Locate regulators in remote areas where there are no people and there is no problem. Unfortunately, this doesnt work either unless you buy 100 acres, someone will build a house nearby and then complain about the noise. Also, there is the problem of employees working in a noisy environment and teh resultant ear damage. From a practical standpoint, there are three methods of noise control. The first is to install a control valve which does not generate unacceptable noise. The second solution is to fabricate a barrier between people and the noise. This barrier may be pipe insulation, an insulated building, buried pipe and equipment, floored pits, distant property boundaries, extra heavy pipe, or any other method you may think of for your particular circumstance. The barrier method chosen will depend on the sound level and whether the problem is due to neighbor complaints or due to OSHA requirements. A third method is to install ciloacero which will absorb a portion of the sound and reduce it to an acceptable level.
