Matt Sneddon

Matt Sneddon has over thirty years’ experience conducting a broad variety of acoustics and vibration consulting, research, and testing activities. Much of this work has been interdisciplinary, involving acoustics, signal processing, materials science, and software development, and on projects ranging from small consultations to large multi-year R&D initiatives. He is equally at home managing the activities of project teams, mentoring technical staff, and working hands-on in direct technical roles.

Major project experience includes an extensive range of acoustic test & measurement programs, transportation and community noise studies, as well as modeling, simulation, & software development tasks. Recent activities include developing improved methods for modeling elastic wave propagation through soils, and characterizing the behavior of high transmission-loss acoustic metamaterials.
