Control of structure borne noise and vibration from sources external to a performance hall
is one of the most important design features of modern performance facilities. Location of
new performance halls near or over rail facilities; in downtown or central areas; within or
as part of multipurpose buildings; and near to parking and central plant facilities can all
lead to structure borne noise impact on the performance space. There is a wide range of
noise and vibration sources which should be considered significant and included in the
structural design review and isolation design provisions. This paper presents discussion of
the basic principles of large performance hall structural isolation including review of
effective modeling and noise control prediction. Also included are the identification of
practical materials and design configurations which can achieve the noise control needed.
The design can consist of base isolation of the entire building, however; isolation of the
performance space within the building, a box-in-box configuration, is usually more
practical and two examples are presented and discussed. There are also frequently other
structures or features which must be supported on the isolated hall without compromising
the noise isolation and two examples of this type of structural isolation are reviewed.
