Ballot Participation

ASA encourages stakeholders from across the globe to participate in the balloting process. However, in order to vote, organizational membership is required but commenting is as simple as requesting a copy of the draft and a comment form. Once you request a copy of the draft, however, 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 access our membership application, please visit: https://asastandards.org/#membership

Open Ballots

If this is your first vote find your ballot number and click on that link to proceed. Important: To vote, find your ballot number and click on that link to proceed. This will prompt you to log-in. If you are participating in more than one ballot or you are changing a vote on a particular ballot during this ONE session, you should “refresh” your browser on this page, before you click the ballot link. Depending on the browser, some will go directly to the ballot and others will get another log-in prompt. If you get the log-in prompt, please refresh once again while on the log-in page. This should open your ballot.
