SOUND-ABSORBING AND SOUND-INSULATING APPARATUS
Sound-absorbing and sound-insulating apparatus (100) comprising a wall element (200) and a plurality of linear elements (300), spaced on a sound-dissipation side of the wall element (200); each of the linear elements (300) comprises a box- shaped body (500); the box- shaped body (400) comprises at least one internal cavity (600) and at least one opening (400) communicating between an enclosed volume of the at least one internal cavity (600) and an outer environment, so as to constitute at least one acoustic resonator to absorb a sound emission directed against the sound-dissipation side; the box-shaped body (500) has the cross-sectional profile having a substantially rectangular shape; the at least one opening (400) is positioned on an upper and/or lower side of the box- shaped body (500); on a cross-sectional profile of the box- shaped body (500), the at least one opening (400) at least partially spans along a direction (40) which is perpendicular to a development plane (41) of the wall element (200). The box-shaped body (500) comprises one or more internal walls (501) configured to define a plurality of internal cavities (600) inscribed within the cross-sectional profile. Each cavity of the plurality of internal cavities (600) is directly in communication with the outside of the cross-sectional profile through a respective at least one opening (400) communicating between the enclosed volume and the outer environment.
