In medical settings, acoustical privacy is important for both patients and medical practitioners. In its interior fit-out of the Whitman Walker Hospital in Washington, D.C., Perkins+Will specified Wave tiles from the Mura collection by Kirei for the client services areas in the 25,000-square-foot outpatient clinic. Wrapping the ceiling as well as the wall with the NRC .55 tiles helps keep conversations—that may include sensitive and personal patient information—confidential, and enhances the clarity of speech, which can reduce stress on clinicians and staff, who must be able to hear clients clearly. The distinctive surface treatment acts not only as a sound buffer, but also as a wayfinding strategy, identifying reception areas throughout the space. Made of recycled material, the lightweight tiles are installed with a speed-clip system.
