Wallace Clement Sabine, the Father of Architectural Acoustics. This book is an invaluable treasury of acoustical case history problems and their solutions. The eleven papers in the book are as insightful today as when Sabine first wrote them. They constitute a primer in architectural acoustics – straightforward and easy to follow, not just for the professional engineer and architect, but also for people who are not acquainted with the physical sciences. No doubt when engineers and architects hear of a book such as this – a collection of papers written by a theoretician, no less a Harvard professor – they will think of the book as an academic tome of little practical use. Wrong! This book shows us clear, simple methodology for solving today’s acoustic problems.
The quintessence of Sabine’s acoustical insight is encapsulated in two simple statements: (1) simultaneous sounds should preserve their frequency balance and (2) successive sounds should remain clear from each other and extraneous sounds. The three fundamental elements of architectural acoustics are loudness, reverberation and resonance, and interference, echoes and other phenomena are but subsets of these elements. Sabine explains that the problems of architectural acoustics require two distinct lines of investigation: one, to determine quantitatively the physical conditions on which loudness, reverberation, resonance and allied phenomena depend; the other, to determine the intensity that each of these elements should have, what conditions are best for the distinct audition of speech, and what conditions are best for music in its various forms. The first is based purely on scientific grounds; the second is a matter of judgment and taste.
The spirit of Wallace Clement Sabine, this clear-thinking genius of architectural acoustics, shines ineluctably through time to reach us, as pure as when his words were first penned. This gem of a book is a must-read for every architect, builder and room acoustician.
