LIRR Pennsylvania Station, New York, New York · OAA developed noise control features for a new 34th Street entrance to the LIRR portion of Pennsylvania Station.  This included noise control of air conditioning equipment serving the LIRR Station.

Midcounty Expressway I-476, Swarthmore, Pennsylvania · Carried out a noise impact analysis upon the campus of Swarthmore University for the proposed Blue Route prior to construction.

PATH Station, Hoboken, New Jersey · Evaluated proposed ventilation systems and identified needed sound and vibration control measures.

No. 7 Subway Line Extension, New York, New York · Acoustical engineering of the 34th Street Station interior to reduce reverberation and train noise for better sound system intelligibility for this $2.1 billion project.  Design of sound isolation and ventilation system noise control to reduce environmental impact.

Highway Sound Barriers, Llewellyn Park, New Jersey · Interstate Route 280 bisects Llewellyn Park, site of Thomas Edison’s Estate and numerous large residences.  The Llewellyn Park Association retained OAA to support litigation to have the New Jersey DOT construct sound barriers to mitigate highway noise.  Based on the resulting sound surveys and noise modeling, the Association was successful at having the barriers constructed.
