not provide the appropriate sound attenuation necessary for satisfactory acoustical
performance. Reverberant sound in the large open display areas must be absorbed
and controlled to avoid distractions to customers and staff. The use of fabric baffles
and/or ceilings with high NRC values are recommended. The NRC for these materials
should exceed .90 and provide a surface area of at least 50% of the ceiling area
(horizontal projection). Walls and floors should also contribute to sound absorption,
whenever and wherever possible.
To avoid the transmission of noise from the Equipment Repair area and similar spaces
into the customer areas, provide floor-to-structure partitions with an STC equal to or
greater than 45. Insure that all openings are protected and dampened for sound and
avoid direct transfer ducts through the partitions.
