Book Description
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 Description
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 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.

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.
