Spring Issue 

Our goal for Acoustics Today (AT) is that each article be interesting to, and readable by, every member of the Acoustical Society of America (ASA). Thus, I encourage everyone to take a look at each article and each “Sound Perspectives” essay in this issue. I trust most people will find something of interest and/or value in each. The first article by Grant Eastland discusses computational methods in acoustics. Grant provides an insightful introduction to the topic and explains complex issues in ways that will help many readers appreciate that the techniques discussed could apply to their own research.
