Randall Rehfuss is an acoustics consultant with Thornton Tomasetti specializing in building acoustics and noise and vibration control. With a background in architecture, he helps project teams solve complex, real-world acoustic challenges while keeping the needs of the people who use the space front and center. He shapes room acoustics, improves sound isolation, controls mechanical and HVAC noise and vibration, and mitigates exterior noise. His expertise includes sound privacy, speech intelligibility, structural vibration, environmental acoustics, vibration-sensitive spaces, and equipment and building-system noise. Randall brings a design-minded approach to healthcare and behavioral health facilities, laboratories, government buildings, and other institutional and commercial projects, and supports mass-timber, secure government, and other specialized projects that benefit from thoughtful coordination across disciplines. He regularly shares his knowledge through AIA-accredited education for design professionals.
