Practical Approaches for Accoustic Construction
Doors to these rooms could be either good quality solid core
dows to interior spaces (corridors and lobbies), with 2
wood or packed metal doors with acoustical seals or spe-
to 3 inches between panes. Line the space between panes
cially manufactured sound control doors. Double glaze win-
at jamb, sill and head with an inch of fiberglass.

This table shows recommended ceiling treatments for different room types, depending on type of roof
construction. It indicates the most cost effective combination; other ceilings are possible if they meet cri-
teria discussed in the text.
1.
Ordinary acoustic tile suspended (also provides acoustic absorption).
2.
Ordinary acoustic tile suspended, under resiliently hung gypsum wall board ceiling.
3.
Absorbent panels (fiberglass, etc.) - (provides no isolation).
4.
Absorbent panels under resiliently hung gypsum wall board ceiling.
5.
STC rated acoustic tile (35-44 STC) (provides absorption and isolation).
6.
STC rated acoustic tile (35-44 STC), plus gypsum wall board ceiling.
7. Absorbent panels below gypsum wall board ceiling.
N.R. not recommended
*This assumes the roof of the Main Rehearsal Room is not continuous with the roofs of other music spaces. If
otherwise, higher quality constructions are required.
