Acoustical Evaluation of Station Upgrades PSE&G West Orange Switching Station, West Orange, NJ 5 June 2024 Page 9 Existing Conditions An acoustical model was developed for the sound contributed by the existing on-site equipment with all operable transformer cooling fans ON and all HVAC equipment ON. Figure 3 shows the results. Results from Figure 3 show that modeled existing emissions for the as-found conditions agree well with field measurement results. Since there is good agreement between the model and on-site measurement locations, the model can be relied upon to predict sound emissions elsewhere. At Receptors D and E, the closest residences to on-site noise sources, emissions are 46 dB(A), 4 dB below the nighttime residential limit. At residences to the northwest, typified by Receptor A, emissions are 26 dB(A), well below the code limit. Maximum emissions at commercial properties are 48 dB(A), as shown at Receptor C. Site sound emissions meet the commercial 65 dB(A) limit by wide margins. It is worth noting that the gray, 50 dB(A) contour, which corresponds to the nighttime residential limit, does not extend past the property line in the direction of the residences. Model results show that emissions at all nearby receptors comply with applicable code limits.
