Title
Standard Test Method for Evaluating Masking Sound in Open Offices Using A-Weighted and One-Third Octave Band Sound Pressure Levels
ASTM International
Publication Date:
Apr 10, 2002
Scope:
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.
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.
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.
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.
