This book covers the architectural acoustics of rooms and buildings from theory to practice, with an emphasis on design and simulation. The text begins with the basics of sound waves and fields, and then explores sound absorption and transmission, perception, parameters, absorbing materials, predictions, insulation, flanking transmission, and electro-acoustics. Presenting worked, real-world examples as well as the latest developments, the authors provide a solid background for designing venues with satisfactory acoustic environments that eliminate noise transmission and offer optimal acoustical conditions for speech or music.
