In-service Experience with Traffic Noise Barriers


Book Description

This synthesis will be of interest to highway environmental engineers, noise analysts, design engineers, maintenance personnel, planners, administrators, and others responsible for the design, selection, and maintenance of noise barriers or other traffic noise abatement policies. Information is provided on current state practice associated with noise abatement techniques and on the various products that are used. This synthesis describes the state of the art with respect to traffic noise abatement procedures, especially noise barriers. This report of the Transportation Research Board provides information on the design, construction and maintenance of both new (Type I) and retrofit ( Type II) noise barriers. The design elements that are addressed include materials, the selection process, service life, foundations, drainage, aesthetics, and safety. The construction section covers technical problems related to surface effects, durability, snow damage, and costs. Other noise abatement measures such as insulation and highway design alternatives are also addressed. The issue of public demand and availability funding is included, and recommendations are made to improve the situation.




Environmental Noise Barriers


Book Description

Noise pollution generated by transport is acknowledged to be a major environmental problem. This book examines both the acoustic and landscape issues affecting the design of barriers. By addressing the needs of the whole design team, it provides expert guidance on good practice and highlights the pitfalls of poor design. Detailed consideration is g




Guidelines for Evaluating the Performance of Highway Sound Barriers


Book Description

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the HITEC evaluation plan for U.S. Gypsum's Sight and Sound Screen. The Sight and Sound Screen is a post-and-panel wall system designed to act as a sight and sound barrier for highways and as a privacy system for residential and commercial property owners. The HITEC evaluation will measure the performance of the barrier against the criteria presented in this report, which reflect the needs of the highway community. Although this evaluation plan was tailored to one product, as a service to state and local transportation officials the report was expanded to provide guidelines that can be adapted for use with other types of sound wall systems.

Handbook of Environmental Acoustics


Book Description

Because environmental acoustics has a complex mathematical basis,it is often difficult to determine whether acousticalrecommendations are valid. Handbook of Environmental Acousticssimplifies this decision-making process and provides easy-to-followexplanations of acoustic terminology, noise control design, andregulatory noise issues. The book clarifies key aspects ofenvironmental noise in basic language, covering: * Common noise sources--including the risk of exposure to commondaily environmental noise sources * Current noise regulations, guidelines, andstandards--illustrating all key points * Acoustic terminology and environmental noisedescriptors--providing a foundation for understanding noiseissues * Effects of noise on people and animals--emphasizing theimportance of restricting noise exposure * Relevant noise rating methods--clarifiying the use of noisemetrics * Construction and building code requirements--explaining currentrequirements and featuring tips on how to avoid privacyproblems * Measurement considerations--demonstrating standard methods andoffering practical advice on how to ensure proper measurementprocedures * Noise control designs--detailing source-path-receiver systems andnoise control fundamentals In addition to traditional noise control methods, new areas, suchas active noise control, sound intensity measurement, and diffusivedesigns, are explained. A sample municipal noise ordinance helpsthe user to draft an ordinance tailored to the needs of aparticular community. Avoiding complex mathematics and analyses,Handbook of Environmental Acoustics is a user-friendly manual forurban planners, municipal officials, engineers, attorneys,industrial hygienists, architects, environmental professionals, andstudents in these fields.










Evaluating Pavement Strategies and Barriers for Noise Mitigation


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Report 738: Evaluating Pavement Strategies and Barriers for Noise Mitigation presents a methodology for evaluating feasibility, reasonableness, effectiveness, acoustic longevity, and economic features of pavement strategies and barriers for noise mitigation. The methodology uses a life-cycle cost analysis to examine the economic features of mitigation alternatives, the FHWA Traffic Noise Model to integrate the noise reduction performance of pavements and barriers, and on-board sound intensity measurements as an input to the prediction model. The appendixes contained in the research agency's final report provide elaborations and detail on several aspects of the research. The appendixes are not included with the print version of the report, but are available online." --Publisher description.
