In this talk, Dr. Barnard will discuss the development of the carbon nanotube (CNT) thermophone and its application to active noise cancellation in pipe and duct systems. Thermophones are solid state speakers that create sound through thermoacoustic oscillations. Using CNT thin films, thermophones are practical for the first time since their inception in the late 1800s. A background on CNT thin films for thermophones will be given. Thermophones provide the most value in applications that require low weight, low volume, and conformal geometries. Dr. Barnard will discuss the application for thermophones in HVAC and exhaust active noise control as well as MTU’s journey in commercialization of the coaxial CNT thermophone.

Dr. Barnard has interests in mechanical vibration, noise control, and acoustics. Since joining MTU, Dr. Barnard has worked on commercializing applications of carbon nanotube thermphones. He completed an NSF I-Corps site program and national I-Corps cohort for initial customer discovery of a coaxial thermophone for noise cancelation in pipe and duct systems. In April 2017 at the World Congress of the Society for Automotive Engineers (SAE), he competed in and won the Global Automotive and Mobility Innovation Challenge (GAMIC) with this technology. In 2020, he co-founded NanoSound Inc. with a former student, Steven Senczyszyn, to pursue commercial applications for carbon nanotube thermophones.

Dr. Barnard is an Associate Professor of Mechanical Engineering and Director of the Great Lakes Research Center at Michigan Technological University (MTU). He holds a B.S. and M.S. in mechanical engineering from MTU and a Ph.D. in Acoustics from Penn State. Dr. Barnard is Board Certified by the Institute for Noise Control Engineering (INCE-USA) and is an associate editor for Noise Control Engineering Journal (NCEJ). Dr. Barnard has been with MTU for 7 years and prior to this appointment, he spent 8 years as a research associate at the Applied Research Laboratory at Penn State (ARL/PSU).
