As more and more commercial interiors, from offices to schools, veer toward open concepts and exposed structures, the spaces become susceptible to noise. And for occupants, excessive noise can lead to increased stress, lower productivity, decreased focus, and poor communication. This session will help architects understand the challenge by exploring how sound is generated, transmitted, and reverberates. Attendees will learn a simpler approach to sabins, how to calculate absorption, and how to apply that knowledge to designing ceiling systems that hit the sweet spot for noise reduction.
