摘要

The shield has walls (3, 5) formed from sound damping and/or sound-absorbing material (4), where the shield forms a chamber (1). An opening (6) and a lock (7) are provided for adjusting sound intensity or sound level of a sound-producing and sound-radiating body (2), where the sound level of the sound-producing and sound-radiating body is influenced by the formation of the opening and the lock. The opening is steplessly closed by using the lock.
