Architectural Acoustics presents a comprehensive technical overview of the field at a level suitable for working practitioners as well as advanced undergraduate or introductory graduate architecture or engineering course. The book is structured as a logical progression through acoustic interactions. Beginning with an architectural history, it reviews the fundamentals of acoustics, human perception and reaction to sound, acoustic noise measurements and noise metrics, and environmental noise. It then moves into wave acoustics, sound and solid surfaces, sound in enclosed spaces, sound transmission loss, sound transmission in buildings, vibration and vibration isolation, noise transmission in floor systems, noise in mechanical systems, and sound attenuation in ducts.

Chapters on specific design problems follow including treatment of multifamily dwellings, office buildings, rooms for speech, sound reinforcement systems, rooms for music, multipurpose rooms, auditoriums, sanctuaries, and studios and listening rooms. While providing a thorough overview of acoustics, it also includes the theory of loudspeaker systems and sound system modeling as well as an in-depth presentation of computer modeling, ray tracing and auralization. It will be particularly beneficial for architects and engineers working in fields where speech intelligibility, music appreciation, and noise isolation are critical.

* Comprehensive guide to the basics of acoustical science and its applications to architectural design.
* Author is renowned expert engaged in acoustical engineering for 20 years
* Covers the latest environmental regulations and health and safety research related to sound inside and outside of buildings.

Architectural Acoustics offers a comprehensive overview of acoustical science at a level suitable for either advanced undergraduate or introductory graduate courses in architectural design and architectural engineering. The text is organized according to how sound interacts with built structures, going from simple geometries through complex building structures. The book begins with a brief but useful history of architecture and the role of acoustics, as well as overview of human perception of, sound, and then progresses through topics ranging from acoustic measurement, noise metrics and environmental noise, to sound in enclosed spaces, sound transmission in buildings, vibration and vibration isolation, and noise in mechanical systems.Architectural Acoustics also includes more advanced chapters on specific design problems, including treatment of multifamily dwellings, office buildings, sound reinforcement systems, rooms for music, multipurpose rooms, auditoriums, sanctuaries, and studios and listening rooms. Also covered is the theory loudspeaker systems and sound system modeling as well as in-depth presentation of computer modeling, ray tracing and auralization.* Comprehensive guide to the basics of acoustical science and its applications to architectural design. * Author is renowned expert engaged in acoustical engineering for 20 years* Covers the latest environmental regulations and health and safety research related to sound inside and outside of buildings.
