OAA assists utility project development teams with new equipment specifications and equipment replacements at electrical switching stations, electrical substations, and natural gas metering and regulating stations. Most projects involve support for local approval by municipal boards. Noise sources of concern include electrical transformers, gas-insulated switch (GIS) buildings, emergency generators, wall-mounted air conditioning units, and gas valves. OAA supports project teams with noise analyses using 3-dimensional computer modeling, development of noise control measures, report preparation, and expert witness testimony.
