HIGHWAY NOISE MITIGATION PROJECTS IN THE UNITED STATES: A CONSULTANT'S PERSPECTIVE

Recent advances in acoustical instrumentation, data processing technology, computer-aided design, and new acoustical models significantly changed the "typical" acoustical project in civil and environmental engineering. Leading engineering companies and state highway agencies throughout the country have been able to provide excellent noise mitigation services that just ten years ago had been a prerogative at a specialized acoustical firm or research institution. In addition, the overall awareness of the noise and vibration issues among general public environmentalists and state transportation officials increased tremendously during the same time period. As a result a wider implementation of the latest acoustical research has been seen in civil engineering projects around the country. The major areas are tire/pavement noise mitigation, road construction materials and technologies, noise barrier materials, design, and construction, and public perception of the noise mitigation projects. This paper also presents an example of a successful collaboration between consulting community, university research, and a civil engineering industry aimed to address growing public demand for a better acoustical environment.
