Abstract
La barriera di sicurezza stradale comprende un corpo (2) di calcestruzzo, cemento o simili materiali, a cui è associato almeno un contenitore (8) presentante almeno una cavità interna (12) posta in comunicazione con l'esterno da almeno un condotto (17) e riempita almeno parzialmente da materiale avente proprietà fonoassorbenti (20, 22).Tale contenitore può così fungere da risuonatore di Helmholtz. (Figura 1)
