Bradley L. Nicholas

Principal Consultant Specializing in Federal Programs, Aviation, Construction & Architecture, and Parks & Recreation

As a Principal Consultant in HMMH’s Aviation Environmental Services (AES) group, Brad’s responsibilities include a range of technical, project management, and training duties. He draws on his education in physics and acoustics as well as his experience as a high school physics teacher to solve acoustical measurement and modeling problems, and presents the results to clients and the public in an approachable way. Brad has broad experience in FAA noise models, such as the Aviation Environmental Design Tool (AEDT) and is the lead instructor for HMMH’s AEDT workshop and Airport Noise Control Practices course.

Additionally, Brad takes the lead on HMMH’s ground noise monitoring for airport noise analysis projects. These projects typically involve detailed measurement programs and noise calculations in specialized models to account for noise source spectra and directivity and the effects of terrain, buildings, barriers, ground types, and vegetation. He recently completed a study of taxiway and ramp noise at Logan International Airport  in Boston, MA and a tree removal study at Dillant-Hopkins Airport in Keene, NH.

Brad holds an M. Eng. in Acoustics from Pennsylvania State University, an M.A. in Education from the College of William & Mary, and a B.A. in Physics from Franklin & Marshall College.


If Brad is doing something for fun it’s probably musical in nature. He started playing guitar back in college, but now spends more time playing upright bass and mandolin. He has also built a few instruments over the years including an acoustic guitar, a mandolin, a ukulele, and an electric bass.
