Arcgeometer is an acoustic architecture studio that specializes in shaping objects, surfaces, and rooms for sound. We see acoustic products as the evolution of objects and ornamentation, and believe in leveraging all elements of rooms for acoustic performance. We develop and apply advanced methods in design, research, and consultation to intentionally move toward a better, more intrinsic acoustic architecture.

Zackery Belanger spent the 1990s immersed in physics, the 2000s working as an acoustician, and the 2010s rethinking the relationships between architecture and acoustics. His expertise lies in the shaping of materials for sonic performance, from the small scale of pores and fibers to the large sweeping curves of rooms. He was the inaugural Researcher-in-Residence at the Experimental Media and Performing Arts Center (EMPAC) at Rensselaer – a building for which he was a design team member – and is the author of the essay Acoustic Ornament. He founded Arcgeometer in Detroit in 2017. CV

Elizabeth Teret spent many years as a musical instrument builder, working for Mason and Hamlin Pianos and Bourgeois Guitars. She holds a Bachelor’s Degree in English from Oberlin, and earned a Master’s Degree in Architectural Acoustics from Rensselaer in 2015. Since then, she has been an assistant professor at Berklee College of Music, where she teaches acoustics and the technology of musical instruments. She lives in Maine, where it’s mostly quiet.

Shireen Mehrpay resides in Hamtramck, MI, where she has been involved in the local experimental music scene for several years. She spends a large amount of time exploring ways to perceive and arrange sounds into music, and now extends her interest and skills into the field of acoustic architecture.
