ASA Standards
NEWLY PUBLISHED, RECENTLY REVISED, AND REAFFIRMED STANDARDS
Visit the ASA Online Store for the most current standard and technical report available!
ASA has a robust portfolio of nearly 165 standards, technical reports, and projects under development—covering a wide range of topics and disciplines in acoustics. As a premiere acoustical society, we bring together diverse expertise and voices ranging from practitioners, government, academia, researchers, and users who collectively and collaboratively advance the direction and impact acoustics has on the global marketplace.
Our volunteers and organizational members are always working—developing new projects, revising existing standards and technical reports, and reaffirming those that are globally disseminated and widely used.

AMERICAN NATIONAL STANDARD
Measurement of Sound Pressure Levels in Air
ANSI/ASA S1.13-2020 (Revision of ANSI S1.13-2005)
ASA Online Store
Abstract
This standard specifies requirements and describes procedures for the measurement of sound pressure levels in air at a single point in space. These requirements and procedures apply primarily to measurements performed indoors but may be utilized in outdoor measurements under specified conditions. This is a standard applicable to a wide range of measurements and to sounds that may differ widely in temporal and spectral characteristics; more specific American National Standards complement its requirements. This standard applies only to the measurement of continuous sounds, those whose duration is 1 second or greater and does not apply to the measurement of impulsive sounds whose duration is less than 1 second. This standard is intended to be used by practitioners in the field. This is a replacement for a previous version of ANSI S1.13.
AMERICAN NATIONAL STANDARD
Declaration and Verification of Noise Emission Values
of Machinery, Equipment, and Products
ANSI/ASA S12.61-2020
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 for a batch of machines, equipment, or products and the requirements for their presentation; the method for determining the mean A-weighted sound power level; the method for optionally determining the total standard deviation; the method for optionally determining the mean A-weighted emission sound pressure level; and the method for verifying the noise emission values that are declared by manufacturers and other product suppliers.
BALLOT PARTICIPATION
ASA encourages stakeholders from across the globe to participate in the balloting process. In doing so, you play a part in providing crucial input—this not only raises value, it ensures consensus.
In order to vote, organizational membership is required but commenting is as simple as requesting a copy of the draft and a comment form. Note, however, that once you request a copy of the draft, we do expect you will return your comment form – and we also require that you do so before the close date.
To participate in commenting on an open ballot, please reach out to us at standards@acousticalsociety.org. To learn about the benefits of becoming an organizational member, or to download our membership application, please visit https://acousticalsociety.org/asa-standards-organizational-membership/.
