摘要

The soundproof screen (1) comprises a soundproof screen edge which has a curved surface that runs perpendicular to the soundproof screen edge. A diffraction edge is formed, such that it runs parallel to the soundproof screen edge which is the upper edge (7) or side edge of the soundproof screen. The curved surface section comprises partial sound-absorbing material.
