Visit the ASA Online Store for the most current standard and technical report available!
ASA has a robust portfolio of more than 150 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.
