<p>An upright for acoustic barriers comprising a main body (2) having a prevalent direction of development (A), a first array (11) of fins (11a) comprising at least three fins (11a) protruding from a first lateral surface (3) of the main body (2) along substantially parallel directions and with concurrent orientation. The upright further comprises a second array (12) of fins (12a) comprising at least three fins (12a) protruding from a second lateral surface (4) of the main body (2) along substantially parallel directions with concurrent orientation. Each array (11, 12) of fins (11a, 12a) defines at least two substantially parallel channels (13) for housing sound-absorbing panels (14).</p> |
