Standard Guide for Architectural Design and Installation Practices for Sound Isolation between Spaces Separated by Operable Partitions

Importancia y uso:

3.1 Rooms formed by operable partitions often need to be isolated acoustically. Sound-isolating properties of operable partitions are specified by architects in terms of sound transmission class (STC) and so advertised by the manufacturer on the basis of laboratory tests in accordance with Test Method E90 and Classification E413.

3.2 Because normal building design and construction practices are not the same as those used in acoustical laboratories, actual field performance of partitions, including operable partitions, will probably be less than that of test specimens. Sound transmission between areas to be isolated will occur through all of the connecting building components in addition to the operable partition, that is, floor and ceiling slabs, ceiling plenums, common walls, etc. All possible paths between the areas being isolated should have a sound insulation performance at least equal to the operable partition. Unless good acoustical practice is followed in both building design and installation, there may be a significant discrepancy between the sound isolation expected and that achieved.

3.3 Because of the complex nature of the sound flanking paths adjacent to operable partitions, it is highly recommended that all related construction details be reviewed by a person qualified in acoustical design and construction.

3.4 This guide does not specify requirements. However, persons desiring to write installation and construction specifications may find the contents useful in developing requirements for the building design site preparation, and installation practices necessary to minimize leakage and flanking sound around the operable partition.
