Noise control measures for surface transportation systems frequently require sound absorptive liners and barriers which must function efficiently and maintain structura integrity over a wide range of environmental extremes. Desirable features of such structures are reviewed. Alternative materials and methods of construction are suggested resulting in economic structures which satisfy both acoustical and non-acoustical requirements.
