Download or read book Design of Wood Highway Sound Barriers written by and published by . This book was released on 2001 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: As new and existing U.S. residential areas and high volume highways continue to intermingle, traffic noise abatement procedures continue to be important. This study investigated the acoustic effectiveness, public acceptance, and structural requirements of various designs and types of sound barriers. In addition, the acoustic effectiveness of a prototype sound barrier is reported. Results are presented on the acoustic effectiveness from in situ measurements of one cement bonded composite panel barrier and four precast concrete, two plywood, two glued-laminated, and three post and panel barriers. The research on public acceptance of sound barriers focused on the perception of visual compatibility. Based on results from semantic-differential and individual ratings, wood and concrete barrier designs were perceived to have favored gbsruralgcs qualities. Data collected during the research on acoustic effectiveness and public acceptance were used to develop structural requirements and construction details for a prototype wood sound barrier. The prototype wood sound barrier provided insertion losses of 15 dB or greater, exceeding the 10-dB acceptable performance for a highway sound barrier.

Book Synopsis Problems with the Performance of Wooden Noise Barriers by : Amy J. Sterling
Download or read book Problems with the Performance of Wooden Noise Barriers written by Amy J. Sterling and published by . This book was released on 1984 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 1984, the Research Council was requested by the Virginia Department of Highways and Transportation to conduct an investigation into the problems experienced with wooden noise barriers. Some of these barriers warped even before construction was completed, and gaps and splits were noted within a short period of time. A questionnaire survey of eleven states that have constructed noise barriers revealed that these problems are widespread. An analysis of the responses to the questionnaire has led to three basic recommendations. The first of these recommends upgrading the overall quality of the material used in the construction of the wooden barriers. This includes raising the grade of wood required and lowering the moisture content, as well as specifying maximum moisture contents for the wood both before and after treatment. Next, it is recommended that simple changes be made in the design of barriers. Technical alterations such as additional braces, fitted joints, overlapping joints, and angled nailing would help preserve their shape. Also, the use of plywood rather than planks would minimize the number of joints. The third recommendation is that specifications be strictly enforced. Wood, with its tendency to warp and shrink, must be handled correctly if it is to provide a noise barrier that will be effective over a long period of time.

Available in PDF, EPUB and Kindle. Book excerpt: Presents Evidence-Based Guidance on Noise Abatement Methods Solutions for reducing the noise impact of road and rail traffic can be found in the use of natural elements in combination with artificial elements in urban and rural environments. Ground and road surface treatments; trees, forests, and tall vegetation; and the greening of buildings and other surfaces can contribute to powerful and cost-effective noise reduction. Environmental Methods for Transport Noise Reduction presents the main findings of the Holistic and Sustainable Abatement of Noise by optimized combinations of Natural and Artificial means (HOSANNA) research project. This project involved experts from seven countries, and assessed noise reduction in terms of sound level reductions, perceptual effects, and cost–benefit analysis. It considered a number of green abatement strategies, and aimed to develop a toolbox for reducing road and rail traffic noise in outdoor environments. Combines Theory with Practice Broad in both theory and application and based on leading-edge research, the book brings together the findings and their practical use. It details assessment methods for perceived noise, and outlines noise prediction methods that can be integrated with noise mapping software. It also explores the economic benefits and positive effects on urban air quality and CO2 levels. The material is this book: Includes up-to-date results on noise mitigation using vegetation and ground treatments Contains relevant results on innovative noise barrier designs Presents data on acoustic performance of vegetation and soil substratum Provides perceptual and cost–benefit analyses of noise mitigation methods Environmental Methods for Transport Noise Reduction is a helpful guide for noise consultants, city planners, architects, landscape architects, and researchers.

Book Synopsis Development of Standards for Noise Barriers Using Recycled-plastic Lumber by :
Download or read book Development of Standards for Noise Barriers Using Recycled-plastic Lumber written by and published by . This book was released on 1996 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes development of standards for noise barrier systems using recycled plastic lumber for wall sheathing, structurally supported by wood or steel frames, with cast-in-place piers proposed for foundations. Aesthetics are addressed by providing options for sheathing color, frame type, and frame arrangement. The standards developed include design tables for selection of standardized member sizes, column spacings, and foundation dimensions. Also included are tables for estimating materials requirements and costs of selected designs, along with notes on system specifications and construction. The proposed systems are cost-competitive with current systems, and may have long-term economic benefits as a result of greater durability, minimal maintenance, and low life-cycle cost.
Book Synopsis Evaluation of Service Life of Noise Barrier Walls in Illinois by : Dianne H. Kay
Download or read book Evaluation of Service Life of Noise Barrier Walls in Illinois written by Dianne H. Kay and published by . This book was released on 1999 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this project included: development of a means to quantify the service lives of materials used for construction of noise barriers in Illinois; development of a life cycle cost model for the evaluation of alternative materials; and evaluation of the need for potential changes to the Special Provisions for noise barrier construction currently used in Illinois. The project included a survey of all state departments of transportation (DOTs) to develop information on experiences with noise barrier materials and products, which showed that nationwide, less than 1% of noise barriers by length have been repaired or replaced, and that few DOTs use life cycle cost analysis for selection of noise barriers. A comprehensive list of the materials currently approved for use in Illinois by the Illinois Highway Development Council was developed. The current condition of existing Illinois noise barriers was assessed by field observation, and Illinois Department of Transportation (IDOT) maintenance personnel were surveyed to develop information on maintenance histories, costs of repairs, scheduled repair or replacement of barriers, and estimated service lives of barriers in place. Service life criteria were developed considering the structural, acoustical, and aesthetic functions of noise barriers. A life cycle cost model was developed and the relative life cycle costs of existing Illinois noise barriers were computed. Noise barrier specifications supplied by IDOT and the Illinois State Toll Highway Authority were reviewed, and recommendations for improving the organization and content of the specifications were made.
