Blue Ridge Research and Consulting has affiliates who complement our team by providing a comprehensive skill set that can address a diverse range of issues in acoustics. Our affiliates include specialists in Bioacoustics, Machinery Acoustics, Physical Acoustics, Physiological and Psychological Acoustics, and Structural Acoustics.

Kent L. Gee, Ph.D.

Kent joined the Physics faculty at Brigham Young University in 2005 after completing his doctoral work in Acoustics at Penn State.  His areas of research include high-amplitude jet and rocket noise, acoustic source imaging techniques, and the active control of fan noise.  He has developed a nonlinear numerical model for the far-field propagation of noise radiated from military jet aircraft and has extensively analyzed multiple near- and far-field data sets for both model- and full-scale jets.  He helped plan and participated in laboratory jet noise measurements conducted at the University of Mississippi and field measurements of the F-22 Raptor at Edwards Air Force Base.  He is involved in continuing high-amplitude jet noise research with colleagues at Blue Ridge Research and Consulting, The National Center for Physical Acoustics, Wyle Laboratories, and Penn State, and has authored or coauthored well over a dozen papers related to this work.  Dr. Gee has worked with a number of students on the development and application of NAH methods.  He is currently advising two students on the development of NAH methods for aeroacoustics applications.  He has also recently advised a graduate student on a research project involving near-field acoustical holography predictions for a simulated high-amplitude, extended source and a student who used an NAH-related technique to better characterize the radiation from axial cooling fans.  He has designed automated microphone positioning and data acquisition and analysis systems for various measurement applications.   He is a member of AIAA and the Acoustical Society of America.

Victor W. Sparrow, Ph.D.

Victor is Associate Professor of Acoustics in the Graduate Program in Acoustics at Pennsylvania State University. Dr. Sparrow has been a Penn State faculty member since 1990. His interests include all aspects of outdoor sound propagation, aircraft noise, nonlinear acoustics, computational acoustics, structural acoustics, virtual acoustics, and scientific visualization.

Sally has over 25 years of experience in acoustics, vibroacoustics, and high intensity jet noise.  Dr. McInerny earned her Ph.D. from UCLA (1987) where she majored in Acoustics / Aeroacoustics with minors in Fluids and Applied Mathematics.  She was a member of the Technical Staff at The Aerospace Corporation (TAC) where she worked in the vibroacoustics area.  At TAC, she developed a procedure to predict far field acoustic levels generated by "generic" launch vehicles and was in charge of instrumentation, measurement and analysis of launch acoustics for determination of loads (on vehicle acoustics) and environmental exposure of wildlife (far-field acoustics).  From 1993-2007, she was a member of the faculty at The University of Alabama where she has had grants / contracts directly related to jet / rocket noise from TAC, Cambridge Collaborative, National Center for Physical Acoustics, Wyle Laboratories, and Stennis Space Center.  From September 2002 to July 2003, Dr. McInerny was a visiting academic at the Institute of Sound and Vibration Research in Southampton, UK; while there, she taught their first MS level course in Acoustics, worked on a tutorial on rocket noise as well as research on non-linear propagation of high intensity rocket noise, with a focus on data analysis techniques that characterize non-linearity.  Dr. McInerny has been a Professor and Director of Undergraduate Programs in the Mechanical Engineering Department at the University of Alabama at Birmingham since June of 2007

Hush Acoustics LLC was founded by Gary Ehrlich to provide acoustical consulting services for architects, interior designers, engineers, builders, developers, lawyers, contractors, and hotels in the areas of architectural acoustics and environmental noise. Prior to founding Hush Acoustics, he gained over 15 years of experience in the field of acoustics at Wyle Laboratories and Polysonics, Inc., and earned Bachelor of Architectural Engineering degree from Penn State. He holds a Professional Engineering (P.E.) license in the states of Virginia, Maryland, and Florida, and has testified as an expert witness before many local boards. He has taught the acoustics course in the Audio Technology program at American University, and has given presentations for architects and designers and at acoustical society meetings. One of his particular specialties is evaluating transportation noise levels inside buildings; in this area he has written extensively including as principal author of the report entitled Guidelines for Sound Insulation of Residences Exposed to Aircraft Operations, prepared for the Department of the Navy.

Bob is a retired branch chief of the Battlespace Acoustics branch of the Air Force Research Laboratory with over 32 years experience in the study of acoustic generation, propagation and mitigation of the effects of acoustic energy generated from military aircraft.  For over 15 years he led a team of researchers that tackled all aspects of military noise for the US Air Force.  His team was the major contributor to the 1990’s Military “Noise Camps” that disseminated information on all aspects of noise impact on the environment.  His efforts led to a comprehensive approach to determining the effects of noise on people, animals and structures. He served as the AF technical representative on  the DoD Environmental Noise Committee, the NATO CCMS committee and the Federal Interagency Committee on Aviation Noise (FICAN)  His interests include automation of acoustic processing, noise modeling, noise propagation and visualization of data.
