APPLY THE PRINCIPLES OF DESIGN TO THE SCIENCE OF SOUND RECIPIENT OF THE VIRGINIA SOCIETY AMERICAN INSTITUTE OF ARCHITECTS 2014 PRIZE FOR SCHOLARSHIP AND DESIGN RESEARCH Architectural Acoustics Illustrated translates the quantitative and qualitative content of acoustics into the graphic language of architecture. Important to performance space design--as well as surface material selection, room shaping and sizing, building placement and orientation, building skin and barrier composition, space planning, and architectural detailing--building acoustics begins at the earliest stages of schematic design and continues through construction administration. Better building acoustics makes better buildings and architectural acoustics needn't be a mystery. This highly visual guide includes over 350 illustrations that outline the physics of sound and the established methods of mitigating unwanted noise in buildings. With authoritative guidance on the latest materials and techniques, topics include a summary checklist of acoustic design guidelines. The Companion website offers video animations that help readers to: * Understand the fundamental behaviors and movements of sound, including sound level, propagation, and frequency * Select building surfaces with sound absorption (or reflection) in mind * Design to make music fuller and speech clearer * Reduce unwanted noise from both within the room and from outside the room * Master the calculations that direct acoustic design solutions All design professionals should have a clear understanding of how sound and space interact, and Architectural Acoustics Illustrated is a comprehensive, practical guide designed for the visual learner.
MICHAEL ERMANN is an associate professor at Virginia Tech's School of Architecture + Design, and a past undergraduate architecture program co-chairman. He teaches architectural acoustics, design studio, and environmental building systems. Prior to joining the VT faculty, Professor Ermann was an acoustical consultant at Artec in New York, NY and Siebein Associates in Gainesville, FL.
