内容説明

Acoustics of Wood offers a detailed treatment of numerous topics that are valuable to those working with wood in architecture, engineering, acoustics, and the crafting of musical instruments. It presents a comprehensive account of the progress and current knowledge concerning wood acoustics, outlining the anatomy and physiology of wood and the specific applications in which its acoustic properties are relevant. Acoustics of Wood reviews state-of-the-art measurement systems and includes material that has not been widely published. Divided into three main parts, the book describes environmental acoustics, presents acoustics methods for the characterization of the elastic behavior of wood, and discusses acoustic methods for the assessment of wood quality.
