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.

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/.

Scope
This standard provides a set of letter symbols for quantities and abbreviations and recommendations for their use in the science and technology of acoustics. The science and technology of acoustics includes sound, ultrasound, and infrasound in all media. Gases, especially air; liquids, especially water; and solids are examples of media with which acoustics is concerned. Specialties within acoustics that make use of the letter symbols and abbreviations within this standard include, but are not limited to: speech, hearing, music, noise control, vibration, shock, sonar, and transducers. Although remarks and limited short-form information are provided for many of the symbols and abbreviations contained herein, definitions and methods of calculating the various quantities are outside the scope of this standard.
