Abstract: 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.
