Download or read book Design of Wood Highway Sound Barriers written by and published by . This book was released on 2001 with total page 78 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.

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.

This book was released on 1996-01-01 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1997 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The completion of the traffic noise barrier project HAM-71-11.44 in Ohio was met with strong reaction from those living in the project area. Many residents complained that noise levels had actually increased at their location as a result of the project, while others claimed that levels had decreased where they lived. The preliminary assessment project was initiated to determine the nature and extent of any problems that had occurred with the construction of the noise barriers. A two-pronged approach was used for the study. First, a survey of residents was conducted to characterize the residents' perception of changes in noise levels due to construction of the barriers. Second, a physical investigation of the project area was made, which included roadway and barrier geometries, traffic characteristics before and after barrier construction, and acoustical measurements to characterize the noise environment in the project area.
