The invention relates to a noise-protection wall-segment, for example for roads, motorways or railways and such like, said noise-protection wall-segment including transparent sheets, preferably a transparent plastic sheets, and means fixing the sheets. The transparent sheet is shaped around a perpendicular to the installation surface of the assembled noise-protection wall, the term `shaping` being understood to mean vaulting and/or folding. Moreover, in the case of plastic sheets, preferably made of acrylic glass, threads of synthetic material can be embedded in the sheet which counteract splintering in the event of fracture and constitute a recognized bird impact protection device.
