Modulate interior noise generated within a room or space. In addition to standard
commercial construction, two other requirements are necessary to ensure sound control
within the library. The use of carpet throughout the majority of the library areas will help
to minimize interior noise. Acoustical ceiling tiles should be provided throughout a
majority of the facility spaces, except service areas. Acoustical panels should be
provided, where necessary, to meet acoustical criteria. Consider the use of cloth
banners to modulate noise, add color, visual interest, and help provide wayfinding cues.
Consider sound transfer between core functional areas (especially the children's areas),
mechanical and electrical spaces, and staff work areas. Maintaining low noise levels in
the main reading areas is important. Consider extending interior partitions to the
structure above the ceiling. Partitions may be single layer gypsum wall board, but
should have cavity insulation and should be completely caulked at the top and bottom of
the partition. Provide solid core doors for openings onto noisy areas. Use fabrics and
baffles to absorb sound. Provide acoustical baffles in all ductwork that penetrates
sound attenuating partitions. Avoid back-to-back electrical outlet boxes. Consider
glassed-in children's, teen, and information services areas to minimize noise.
