4.1 This guide is intended for the use of architects, engineers, office managers, and others interested in designing, specifying, or operating office environments.

4.2 It is not intended to be applied to other environments, for example, open plan schools.

4.3 While this guide attempts to clarify the many interacting variables that influence acoustical performance, it is not intended to supplant the experience and judgment of experts in the field of acoustics. Competent technical advice should be sought for success in the design of offices, including comparisons of test results carried out according to ASTM standards.

1.1 This guide discusses the principles and interactions that affect the acoustical performance of open and closed offices. It describes the application and use of the relevant series of ASTM standards.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
