The noise level from'fluisterasfalt '[silent asphalt], as it is termed by our Flemish friends, or'ZOAB, zeer open asfaltbeton' [very open asphalt concrete], as we like to refer to it in the Netherlands, is probably 20 decibels lower than that from cobblestone roads.
Hviskeasfalt, sådan som vores flamske venner kalder det, eller ZOAB, meget åben asfaltbeton, som vi kalder det i Nederlandene, er 20 decibel støjsvagere end en vej med brosten.
