Download or read book Acoustic Absorbers and Diffusers written by Trevor J. Cox and published by CRC Press. This book was released on 2004-02-27 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of a room, semi-enclosed spaces and the outdoor environment. Their correct use is important for delivering high quality acoustics. This unique and authoritative text describes how to effectively measure, model, design, optimise and apply diffusers and absorbers. Surface diffusion is a relatively young subject area, and diffuser design, application and characterisation are new to practitioners and researchers, who may not have been exposed to this new information in their formal training. This book is a resource for new and experienced acousticians seeking an understanding of the evolution and current state of the art in diffuser research and practice. Absorption is a more established technology, and so the book blends traditional design with modern developments. By collecting the key aspects of absorbers in one text, the book offers new and experienced professionals an opportunity to understand this subject in more depth. This detailed book serves to cover the practical and theoretical aspects of absorbers and diffusers and is well illustrated, with examples of installations and case studies.

This book was released on 1994 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of materials for underwater acoustic applications requires measurement facilities for characterizing acoustic performance. Existing facilities are generally suitable for making measurements in the frequency range above 1 kHz. These include the pulse tubes located at NSWC/Annapolis and the anechoic tank located at NRL/Orlando. Under the Attenuation Materials Program of the Office of Naval Research, capabilities for characterizing acoustical materials in the frequency range below 1 kHz are being developed and improved. As part of this effort, Cambridge Acoustical Associates has designed and developed a laboratory testing device for evaluating acoustical materials below 1 kHz at hydrostatic pressures up to 500 psig. Several unique testing capabilities are designed into this device. Sufficient measurements are made on inertially-backed samples to obtain a two-port impedance representation of the material. A water layer coupling the excitation piston and the face of the material sample permits realistic loading of spatially inhomogeneous materials under hydrostatic pressure. The design of the device is documented in Ref. 1. In this report the performance of the device is evaluated.
