The National Council of Acoustical Consultants (NCAC) is proud to announce that the recipient of the 2025 Laymon N. Miller Award for Excellence in Acoustical Consulting is David L. Adams, P.E. This award, developed jointly by NCAC and the Institute of Noise Control Engineering of the United States of America (INCE/USA), recognizes individuals who have demonstrated exemplary practice in acoustical consulting over a sustained period of time. The honor is independently bestowed by NCAC in odd-numbered years and by INCE/USA in even-numbered years.
Adams has had a transformative influence on the acoustical consulting profession for more than 50 years. His leadership, technical expertise, and commitment to mentorship have made lasting contributions to clients, colleagues, and the broader acoustical community. From early beginnings in aviation engineering at Boeing, to decades of distinguished work as founder and leader of D. L. Adams Associates, his impact spans continents and industries.
Throughout his career, Adams has played a significant role in landmark projects such as Boettcher Concert Hall in Denver, Colorado and Sala Nezahualcóyotl in Mexico City. Under his direction, D. L. Adams Associates expanded to Hawaii and beyond, completing acoustical consulting projects on all seven continents. He has been a dedicated member and leader within NCAC, including serving as President (1990–1992), and has mentored several future NCAC presidents within his firm.
Beyond his contributions to NCAC, Adams has been active in the Acoustical Society of America (ASA) since 1971, organizing major conferences and championing the advancement of acoustical science. He has also contributed to the development of standards through ASTM International and taught acoustics at the University of Colorado Denver and Wichita State University.
Peers who supported Adams’ nomination highlighted not only his technical achievements, but also his character and influence as a mentor. Russ Berger wrote, “It is Dave’s integrity and generous nature I probably admire the most.” Sean Connolly added, “His influence is perhaps even greater as a mentor and teacher, which embodies the spirit of the Laymon Miller Award.”
The Laymon N. Miller Award recognizes individuals whose work has significantly enhanced quality of life through improved acoustical environments. David Adams exemplifies this mission, having spent his career guiding clients and professionals toward excellence in acoustical design.
The award was presented during a special ceremony at the NCAC Annual Meeting July 25-27 in Denver, CO.
