Pennsylvania Convention Center

Community Revitalizes Sound in Revamped Pennsylvania Convention Center
The recently completed expansion of the Pennsylvania Convention Center (PCC) in downtown Philadelphia is, to date, the largest public works project in Pennsylvania history. The Convention Center, first opened in 1993, was expanded by four full city blocks as part of a 20-year plan to renew Philadelphia’s downtown City Center District, a once-struggling area that has seen tremendous economic growth in the two decades since the revitalization efforts began. The expansion earned PCC ranking as one of the ten largest convention properties in the country. It now spans a massive 2.3 million square feet—20 acres in the heart of downtown Philadelphia—and features two large ballrooms and seven exhibit halls, ample space to hold two major conventions and several smaller events simultaneously. “One of the important elements of the expansion project was the installation of a professional quality audio system that would deliver evenly distributed, clear and natural sounding music and speech reproduction throughout these large spaces,” explained Larry McIntyre, senior consultant at Acentech, the award-winning acoustics, audiovisual, and vibration consulting firm who designed PCC’s new audio system. The sound system, installed by the Philadelphia offices of AVI-SPL, is used not just for delivering music and general announcements, but also to deliver emergency voice notifications. This makes system integrity a critical aspect
