5-1 Using This Chapter
This chapter contains discussions and illustrations of practi-
cal construction methods and typical details for achiev-
ing sound isolation, noise control, and good room acoustics.
The principles behind these techniques have been dis-
cussed in Paragraph 3-5, Acoustical Considerations. The
examples presented are not solutions to all problems,
but aids to understanding how to apply the principles to
achieve a Band Practice Facility that performs success-
fully. The illustrated methods should be useful to archi-
tects in developing Final Designs for band facilities, and
to band personnel and Facility Engineers doing minor
renovations and improvements to existing facilities.
5-2 Sound Isolation
Isolation depends on the design and execution of all barri-
ers that separate one room from another. That includes
floors, roofs and ceilings, walls, as well as door and win-
dow assemblies. Balanced performance is the goal. If a por-
tion of a barrier is weaker than the remainder (for example,
an STC 35 door in an STC 65 wall), the inferior portion con-
trols the isolation achieved. Even before these construc-
tion considerations, planning for appropriate adjacencies
and separations, as discussed in Sections 3-4 and 3-5,
should have been applied, as the most cost-effective means
to obtain isolation.
