When putting together each issue of Acoustics Today (AT), I try to have a diverse set of topics. In particular, a goal is to ensure that we have articles that, over time, represent the extraordinary diversity of research and ideas that make the meetings of the Acoustical Society of America (ASA) so interesting and exciting. I hope that readers find that this issue of AT meets the goal of diversity and that every reader decides that it is worth their time to read every article.
