A useful book that should improve your knowledge of barrier noise control. It has the potential to inspire, to encourage you to develop barriers that are both effective and attractive. Even if you don't have time to read the text, you will gain many ideas merely by looking at the pictures.
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 advisory 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.
* Guides the reader through the links between measurement and theory
* 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.

Practical Instruction on the Art and Science of Acoustic Design and Architecture
Build your own acoustic environments such as recording studios, control rooms, and home listening rooms with expert insights from two engineering professionals. Fully expanded to cover the latest methods and software tools, Master Handbook of Acoustics, Fifth Edition presents clear explanations of acoustic phenomena and provides a hands-on approach to room design. Learn how to perform acoustic measurements, choose room dimensions, assign speaker placement, analyze response curves, and design and install sound absorbers and diffusers. You will also find details on how to fine-tune room reverberation, minimize external noise, and apply psychoacoustic concepts.
Master Handbook of Acoustics, Fifth Edition explains how to:
Determine how sound propagates in open and enclosed spaces
Measure sound-pressure levels and work with decibels
Analyze the characteristics of room modal resonances
Treat rooms for optimal early reflections, reverberation, and diffusion
Minimize acoustic distortion, comb-filter effects, and HVAC interference
Construct high-quality stereo and surround-sound listening rooms
Design personal and professional recording studios and control rooms
Understand the acoustics of auditoriums and concert halls
Optimize room designs using measurement, modeling, and auralization software

Guidelines for the evaluation and measurement of damage levels in buildings from groundborne vibration.
Abstract
This British Standard, a part of the BS 7385 series, gives guidance on the assessment of the possibility of vibration-induced damage in buildings due to a variety of sources, and identifies the factors which influence the vibration response of buildings.
This standard is intended to provide a standard procedure for measuring, recording and analysing building vibration together with an accurate record of any damage occurring.
Vibrations of both transient and continuous character are considered. A method of assessment which takes into account the characteristics of the vibration, the building and the measured data are given.
This standard is applicable only to vibration transmitted through the ground and not to vibration set up by machinery within a building. It does not cover chimneys, bridges and underground structures such as chambers, tunnels and pipelines.
History and related standards
This British Standard should be considered together with BS 7385-1:1990.
