scope:

1.1 This test method specifies the procedures that can be used to evaluate the spatial and temporal uniformity of masking sound in open offices using A-weighted sound levels. It also specifies the procedure for evaluating the masking sound spectrum and level using one-third octave band sound pressure levels. This test method is one of two standards that can be used to evaluate masking sound; the other is Guide E1041. Guide E1041 is used when a more in-depth evaluation of the masking sound is required. It does not allow the use of A-weighted sound levels and requires that more locations in the office space be surveyed to determine spatial and temporal uniformity. Guide E1041 can be used in place of this test method.

1.2 The results of this test method can be used to determine if the masking sound meets a particular specification for spatial and temporal uniformity if that specification is written in terms of A-weighted sound levels and if the masking sound meets a particular spectrum shape and level in the office area.

1.3 This test method must not be used to evaluate the acoustical environment in an office space. It is intended only to evaluate the masking sound in an office. This test method, for instance, does not evaluate the low frequency rumble noise found in some offices.

1.4 This standard does not purport to address all of the safety problems, 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.
