It is estimated that more than 25% of Europeans experience a reduced quality of life due to exposure to environmental noise, with road traffic noise being the most dominant source of environmental noise. In an effort to improve the quality of life for the general public exposed to noise from road traffic, one prominent mitigation measure being used currently is the installation of noise barriers. Infrasonics' Dr. John Mahon recently completed a two year research project with the National Roads Authority (NRA) on the Optimal design of noise barriers for Ireland. As part of this project Dr. Mahon implemented EN 1793 Part 5 and 6, in situ test methods to determine the acoustic performance of a noise barrier. This was the first time such measurements were completed in an official capacity in Ireland. One of the main milestones from the project was the completion of a good practice guide for noise barrier design. The aim the good practice guide is to provide guidelines for the design, installation and maintenance of noise barriers. The document provides some background information on acoustics and the purpose of noise barriers. The document use international policies and experiences from other countries to formulate a comprehensive guidance for noise barrier design.
