LA COUVERTURE ACOUSTIQUE DE L'AUTOROUTE B6 A LA SORTIE DE PARIS

THE LEVELS WERE 69 DB(A) DURING THE DAY AND 74 DB(A) AT NIGHT. AFTER LISTING THE CONSTRAINTS TO RESPECT, THE AUTHOR DESCRIBED VARIOUS SOLUTIONS TO THE PROBLEM AND THE SOLUTION SELECTED WHICH CONSISTED IN BUILDING A SELF-SUPPORTING COVER CONSISTING MAINLY OF A PRETENSIONED STEEL SHELL. THE NOISE LEVEL WAS LOWERED TO 65 DB(A), ESPECIALLY AT NIGHT-TIME. COSTS ARE QUOTED.
