Acoustical Design Collaborative, Ltd
provided room acoustics, HVAC noise control,
and sound systems design for the renovation
of an historic 1852 courtroom. The project
objectives were to restore the courtroom to
its original appearance and to correct
speech intelligibility problems. Acoustical
measurements indicated a combination of room
reverberance, high HVAC noise levels, and
insufficient amplified sound distribution
all reduced speech intelligibility. New
finish materials, including fiberglass
hidden above the overhanging window
cornices, acoustical plaster on the
perimeter coves, heavy velour drapes, and
period carpeting were installed to lower
room reverberation. Acoustical duct lining,
sound attenuators, and resized diffusers
reduced HVAC system noise. A new voice
reinforcement system with automated
electronics to simplify user control and
recessed ceiling loudspeakers provide
uniform sound distribution. The project
received a State of Pennsylvania historic
preservation award upon completion. |
