The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls. To estimate the measures suitability the starting points were to measure the effects on noise, the impact on the landscape, coasts and other possible side effects. It is important that the noise issue may not be replaced by other problems such as barrier effects, significant effects on the landscape or worsening living environment. To assess the reducing effect of the noise, calculations have been made. These showed that the measures that reduce noise spread were more favorable compared to those which prevent noise generation. The most appropriate measure in this case, based on the noise impact and influence on the landscape, is a 2 meter high acoustic screen in a combination of 0,5 meter wood and 1,5 meter tempered
