The Acoustics Group of Symonds Travers Morgan has worked and is currently working on a number of stadium projects which have required a significant acoustic input at various stages of the planning, design and operation phases of the project. Such projects include the Millennium Stadium Cardiff Arms Park, the Hong Kong Stadium, Wembley Stadium and Ibrox Stadium. Some aspects of these projects are outlined in this paper to demonstrate the various noise and acoustic aspects that need to be addressed when dealing with Stadium project.
