Book Description

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes a HITEC evaluation of the Sight and Sound Screen System, manufactured by U.S. Gypsum Co., covering 11 performance issues. The Sight and Sound Screen (sold under the name of Ultrascreen) 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. This report details the test procedures and analysis used to evaluate the system and provides the results. When the results are compared to the results presented in Guidelines for Evaluating the Performance of Highway Sound Barriers, the evaluating panel concluded that the Sight and Sound Screen meets or exceeds all of the applicable evaluation criteria. Prospective users should review these findings for applicability to their local conditions and standards.

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.
