Abstract (en)
A sound barrier (1) arranged to improve the air quality comprises a wall element (10), an air filter element (11) and an air guiding element (12). The air guiding element (12) is arranged to define, together with the wall element (10), an opening (15) which tapers towards the air filter element (11) so as to concentrate wind-propelled air at the air filter element, and force the wind-propelled air through the air filter element. To this end, the air guiding element (12) is preferably curved. The sound barrier is particularly useful alongside major roads and highways, but may also be used at airports.
