Working with design/builder, Three Rivers
Construction, Inc. and audio systems design firm Taipale Media Systems, Inc.,
Acoustical Design Collaborative, Ltd provided room acoustics, sound isolation,
and HVAC noise control design for a new 2,500-seat auditorium used for Worship
and contemporary Christian concerts. Extensive acoustical treatment was
necessary for the auditorium to provide low room reverberance for music and
sufficient ceiling sound reflections for congregational singing and response.
Sound absorptive and diffusing surfaces were specified for the walls and sound
reflecting ceiling clouds were installed below the roof trusses. The rear wall
has several low frequency “bass” traps to reduce the build-up of low frequency
sound energy. Sound isolation was necessary to reduce sound transmission between
the auditorium and adjacent meeting and Worship spaces. HVAC noise control
addressed air handler, duct “breakout”, and diffuser noise generation and
transmission. The rooftop chiller was relocated to grade level to avoid costly
sound isolation for the lightweight building structure. Praise for the acoustics
has been expressed by clergy, congregants, and touring artists. |
