Marshall Long Acoustics was the acoustical and audio visual engineering firm of record on St. Paul the Apostle Catholic Church. Working closely with the architect and the parish, we helped design the architecture of the nave, sanctuary, foyer, cry rooms, and the technical mezzanine. We designed the interior acoustics of the church, which were carefully crafted to provide reverberant support for choral singing.

We also designed the audio visual system in the main worship space for speech and music. It was computer modeled to combine excellent intelligibility, true source localization, and good reverberant character for music. We made follow-up inspections during the installation of the system and assisted with the system setup. The video projectors were designed to project on an area of the front wall just above the stained glass windows. The projectors were not installed during the initial construction due to budget constraints.
