Abstract:
A guard rail is provided with noise-reducing measures and includes a plurality of substantially vertical posts supporting a longitudinal guard rail beam. Furthermore the guard rail is provided with plate-shaped noise-reducing modules attached to the supporting, substantially vertical posts. Advantageously, the guard rail may be perforated so that the sound is allowed to pass into the noise-reducing modules at the rear.
