We’re delighted to announce the recent publication of a newly revised ASA Standard – S12.61-2024, Declaration and Verification of Noise Emission Values of Machinery, Equipment, and Products.
The ASA Standards Program is pleased to announce the newly revised ANSI/ASA S12.61-20XX standard, which provides updated guidelines for measuring and evaluating workplace noise exposure. These revisions improve accuracy, consistency, and alignment with industry best practices, helping organizations better assess and manage noise-related risks in occupational environments.
Abstract:
Information on the acoustical noise emitted by machinery, equipment, and products is needed by consumers, manufacturers, building and land-use planners, governmental authorities, and others concerned about noise in order to make informed purchasing decisions. To meet this need, this standard gives requirements and guidelines for how to properly and uniformly provide product noise level information to the public. This standard specifies the noise emission values to be declared (required and optional) for a batch of machines, equipment, or products and the requirements for their presentation It describes the method for determining the mean A-weighted sound power level; the method for determining the standard deviation of production; the method for determining the total standard deviation; the method for determining the mean A-weighted emission sound pressure level; the method for determining the expanded uncertainty; and the method for verifying the noise emission values that are declared by manufacturers and other product suppliers. This standard is applicable to commercially available products that emit noise, including consumer products and household appliances, information technology products, industrial equipment, outdoor equipment and construction machinery, and other products.
