Trafikverket is constructing noise screens along the E4 motorway<\/a> in the traffic area around Kungens Kurva, south of Stockholm. Skanska is in charge of the project and GreeNest form AB<\/a> supplies the screens in collaboration with production specialists from Malm\u00f6 Arena.<\/p>\n

Sju olika konstruktioner  har utv\u00e4rderats. Sk\u00e4rmarna produceras av GreenEst i samarbete med produktionspersonal fr\u00e5n Malm\u00f6 Arena.<\/span><\/p>\n

Seven different screen designs were evaluated. The measurements in Malm\u00f6 were made according to EN1793-5 and EN1793-6 respectively together with our highly qualified partner Akustix Sp z o. o<\/a>. Metoden bygger p\u00e5 pulsad excitering och m\u00f6jligg\u00f6r att m\u00e4tningar kan utf\u00f6ras s\u00e5v\u00e4l i milj\u00f6er med relativt h\u00f6ga bakgrundsniv\u00e5er som i milj\u00f6er med viss efterklang, i detta fall inne i m\u00e4sshallen, d\u00e5 reflexer effektivt kan elimineras fr\u00e5n uppm\u00e4tt signal genom att applicera ett sk Adr\u00edenne-window<\/a> .<\/p>\n
