AT&T, New Brunswick, New Jersey · Vacant property adjacent to a telephone switching facility was developed with residences 40 feet from the facility emergency generator. This resulted in an exceedance of the local noise code of 23 dB(A) during testing. OAA designed mitigation for the gen-set for compliance with the noise code, achieving a reduction of 35 dB(A) and alleviating nighttime sleep interference.
ADP, Florham Park, New Jersey · Evaluated candidate gen-sets in manufactured enclosures and provided specification to meet local and state noise regulations.
Bell of Pennsylvania, Philadelphia, Pennsylvania · Six emergency generators were planned for the roof of a parking structure adjacent to an academic building at Temple University.
