Hi! I have this book and think that it is a very very good book and very atualized about architetural acoustics because it brings not only the principles of acoustics but a lot of case studies of some famous places with ilustrations, wich are a good reference of the aplication of the design for a acoustical place. And brings too a section about the recent innovations in acoustical design and research. This book and David Egans Architectural Acoustics makes a perfect couple for architects and other people who wants a good knowledge about acoustics in architecture. I really recommend.
