Acoustical Design Collaborative, Ltd
provided room acoustics, HVAC noise control,
sound isolation, and sound system design for
the renovation of a 250-seat recital hall in
the Smithsonian Institution Museum of American
History. A sound focusing concave ceiling
was replaced with a flat coffered ceiling having
elements of varying dimension to enhance sound
diffusion. The ceiling coffers enclose HVAC
ducts and oversized diffusers to achieve an NC-20
noise level necessary for location recording. The
stage was redesigned with an angled ceiling
and improved side wall sound reflecting surfaces. The
ceiling coffers enclose HVAC ducts and
oversized diffusers to achieve an NC-20
noise level necessary for location
recording. The rear exterior window was
modified with a ¾ inch thick glass lite
spaced 2 feet from the existing curtain wall
to reduce aircraft noise transmission.
Interior sound isolation to the adjoining
exhibition galleries was achieved through
custom acoustical doors. The sound system
uses ceiling distributed loudspeakers for
lectures and portable loudspeakers for
prerecorded audio playback. Microphone
inputs are routed back to a recording
control room. The Hall of Musical
Instruments is now a performance showcase
for the Smithsonian’s collection of
Stradivarius, Guarneri, and Amati stringed
instruments played by the renowned
Smithsonian Chamber Players and world-class
guest soloists. |
