Fall Issue 

In the last issue of Acoustics Today (AT), I wrote that we were using a new production group. In this issue, I am pleased to announce two other changes for AT. First, we have added a digital object identifier (DOI) to each article. It is on the bottom of the title page and should be used in citing the article to help easier access. I thank Dan Farrell, webmaster of the Acoustical Society of America (ASA), for setting up the DOIs. Over time, Dan will assign DOIs to earlier issues of AT so that the articles can be accessed more easily.

I also want to thank Dan for his very creative revision of the AT website ( The look of the site has been refreshed and we now have a much more effective approach in navigating to past issues. And “behind the scenes,” Dan has improved access to the PDFs of all past issues of the magazine.

The second addition is that ASA member Dr. Alexandra Tolstoy is now the AT “artist in residence.” When doing the fall 2018 AT issue featuring women in acoustics, we “discovered” that Alex is a truly outstanding watercolorist. So we have invited her to provide paintings with acoustic themes that will appear in some issues. Most will be within the magazine as in the summer 2019 issue. However, Alex recently sent me a painting that captured the theme of several articles in this issue. It is the cover of this issue.
