    Scope - (Show below) - (Hide below)

    1.1 This test method covers the measurement of the interzone attenuation for three components of open-plan spaces:

    1.1.1 Ceiling systems when used in conjunction with partial-height space dividers. This arrangement is commonly used in offices to achieve speech privacy between work zones in the absence of full-height partitions. This test method is applicable to any ceiling configuration, including, for example, a pattern of sound-reflective panels in an otherwise sound-absorptive ceiling. This test method generally requires use of a fixed space divider height of 1.50 m (60 in). In recognition of trends toward alternate divider heights in open office environments, measurements with an alternate divider height may be conducted in accordance with this standard.

    1.1.2 Furniture panels used as acoustical barriers in open-plan spaces to provide speech privacy or sound isolation between working positions.

    1.1.3 Vertical panels, including wall finishes such as sound-absorbent panels, and furniture panels or screens which may reflect sound. It may not be applicable to such items as window finishes or furniture other than panels if these differ significantly from flat wall panels.

    1.1.4 The combination of results from the various components of an open-plan office is beyond the scope of this standard.

    1.2 Unless otherwise qualified, all dimensions specified in this test method shall be understood to have a tolerance of ±6 mm (±1/4 in.) The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
