Acoustic Absorbers and Diffusers

This definitive guide covers the design and application of absorbers and diffusers. Surface diffusion is a relatively young subject area, and diffuser design, application and characterisation are often not well understood by practitioners. Although absorption is more widely understood, it is also informed by new research. This text details the evol

"This revised edition consolidates the research and theory of acoustic materials known to date and will be a valuable resource for acoustic researchers, consultants and acoustic product manufacturers. I would also expect acoustic standards committee members to find useful information If you have an earlier edition, as I do, there is sufficient new material in this edition to recommend purchasing this reference volume."
Noise Control Engr. J.

"This book is a vibrant update of previous editions which incorporates the latest 21st century thinking on absorbers and diffusers and as such it should be in every acousticians possession."
Raf Orlowski, Ramboll Environ

"A valuable treatise in filling a great need to provide the essential basis for anyone who is or may be involved in architectural acoustics research, study, education and design practice."
Ning Xiang, Rensselaer Polytechnic Institute

"The current edition is a must-have in any acoustician's library. Even if you own an earlier edition, the updates and cosmetic reworking of the third edition breathes new life into this now-classic text."

-- Brandon Cudequest, Journal Audio Engineering

"Cox and D'Antonio can still claim authorship to the most comprehensive text on sound-absorptive and diffusive materials."

-- Brandon Cudequest, Journal Audio Engineering
