Sound insulation is an important aspect of building performance. This book is a comprehensive guide to sound and vibration theory and its application to the measurement and prediction of sound insulation in buildings. It enables the reader to tackle a wide range of issues relating to sound insulation during the design and construction stages of a building, and to solve problems in existing buildings. The book has been written for engineers, consultants, building designers, students in acoustics, researchers and those involved in the manufacture and design of building products. Key aspects are that it: * Explains the fundamental theory using examples that show its direct application to buildings * Guides the reader through the links between measurement and theory * Explains concepts that are important for the application, interpretation and understanding of guidance documents, test reports, product data sheets, published papers, regulations and Standards * Makes direct reference to ISO and EN Standards on sound insulation * Contains a large number of illustrations showing measurements, predictions and example calculations for quick reference Carl Hopkins previously worked on building acoustics and environmental noise at the Building Research Establishment. During this time he was involved with sound insulation in research, consultancy, standardization, and building regulations as well as being an advisor on acoustics to government departments. He is currently a Senior Lecturer at the University of Liverpool within the Acoustics Research Unit of the School of Architecture.

The book explains sound insulation in buildings at a level suitable for both graduate students and expert consultants. Theoretical models are set out for sound transmission in buildings, with an emphasis on thick and heavy constructions. Thus, the description is not restrained by the common assumption of bending waves which is characteristic of thin plates, only. A general description is provided, with the modal density in the structures as a key parameter. At low frequencies statistical energy analysis is replaced by modal energy analysis. Sound transmission through windows and facades is represented by a model that allows any angle on incidence, including the special case of grazing incidence. One chapter is devoted to the subjective evaluation of sound insulation, particularly noise from neighbours, and how this can be applied in a sound classification scheme for dwellings. Measurement methods in building acoustics are presented with emphasis on modern methods using MLS signals or sine sweeps. The analysis and estimation of measurement uncertainty is discussed in detail. In a final chapter examples of experimental buildings with high sound insulation are explained.

Investigates if it is possible to lower the standardized frequency range from 100 Hz down to 50 Hz.

Since structure-borne sound plays an important role in noise control, material testing and machine diagnosis, the relevant properties of the most important elements of a construction (plates, beams and shells) are investigated. Measurement techniques, equations of motion, formulas for wave speeds, resonance frequencies, impedances, transmission coefficients etc. are given. The different damping mechanisms and the radiation properties are treated. The statistical energy analysis (SEA) is also presented. This new edition has been enlarged to include also waves on orthotropic plates, and the vibration and radiation of cylindrical shells.

Straw bale building is a radically different approach to the process of building. Like all innovative ideas, it has been pioneered by the passionate, and used experimentally by those with the vision to see its potential. It is firmly based in that sustainable, 'green building' culture that has brought to the construction industry many new and useful ideas about energy efficiency and responsibility towards the environment. As a building material, straw excels in the areas of cost-effectiveness and energy efficiency. This practical guide has been written by the most experienced straw bale builder in the UK. It gives details of all the main construction methods, and includes: * bale specifications * plans * walls and foundations * doors and windows * plastering * building regulations and planning permission * frequently asked questions * construction drawings. This fully revised and updated edition includes new construction drawings, standard details for best practice design, examples of off-the-peg drawings for small buildings such as summer-houses and studios, and designs for affordable houses. These designs meet Building Regulations Code 6 for sustainable homes, and have a carbon rating of less than zero.

This book deals with acoustic wave interaction with different materials, such as porous materials, crystals, biological tissues, nanofibers, etc. Physical phenomena and mathematical models are described, numerical simulations and theoretical predictions are compared to experimental data, and the results are discussed by evoking new trends and perspectives. Several approaches and applications are developed, including non-linear elasticity, propagation, diffusion, soundscape, environmental acoustics, mechanotransduction, infrasound, acoustic beam, microwave sensors, and insulation. The book is composed of three sections: Control of Sound - Absorbing Materials for Damping of Sound, Sound Propagation in Complex/Porous materials and Nondestructive Testing (NDT), Non Linearity, Leakage.

This classic and authoritative student textbook contains information that is not over simplified and can be used to solve the real world problems encountered by noise and vibration consultants as well as the more straightforward ones handled by engineers and occupational hygienists in industry. The book covers the fundamentals of acoustics, theoretical concepts and practical application of current noise control technology. It aims to be as comprehensive as possible while still covering important concepts in sufficient detail to engender a deep understanding of the foundations upon which noise control technology is built. Topics which are extensively developed or overhauled from the fourth edition include sound propagation outdoors, amplitude modulation, hearing protection, frequency analysis, muffling devices (including 4-pole analysis and self noise), sound transmission through partitions, finite element analysis, statistical energy analysis and transportation noise. For those who are already well versed in the art and science of noise control, the book will provide an extremely useful reference. A wide range of example problems that are linked to noise control practice are available on www.causalsystems.com for free download.
