摘要： A device is provided preventing the transmission of sound, the device being fabricated of polymer composition and comprising a hollow core member formed of fiber-reinforced thermosetting resin, and at least outer member formed of unreinforced thermoplastic resin which is friction fit to the core member. The core member and outer members are preferably formed by pultrusion and extrusion, respectively. Adjacently disposed devices are connected together to form a fence-like barrier through which few or no sound waves are allowed to pass. This system is advantageously used to prevent sound waves emanating from a large transportation structure such as a highway, railroad track, or airport.
