Spring Issue 

We are starting a new feature in our “Sound Perspectives” section that will appear in each spring and fall issue of Acoustics Today (AT), a list of the various awards and prizes that will be given out and the new Fellows who will be honored by the Acoustical Society of America (ASA) at the spring and fall meetings (awardees and Fellows in this issue of AT will be honored at the Spring 2019 Meeting). The idea for including this list came from ASA President Lily Wang, and I thank her for her suggestion because inclusion of this list further enhances the ways in which AT can contribute to our Society.
