BULLERPROBLEM INTILL MOTORVÄGAR : Kartläggning av bullernivåer vid Kopparlunden intill E18 i Västerås

This degree project illustrates today's noise problems caused by high-speed highways. The area that has been studied is Kopparlunden along the E18, in Västerås which reflects a long and unique industrial history from the late 1800's. In the current situation the municipality of Västerås is doing a transformation of the existing industry into a modern residential area with the new homes, workplaces and services. The purpose of the work is to identify noise and study traffic-related noise problems in this area, partly to check the result of noise values ​​against the requirements, and to propose noise reduction measures. This work is based on own noise measurements and calculations as well as on the study of a couple of relevant reference objects. The result of own noise measurement and calculations at all four points was about 60 – 63 dBA equivalent on two meter high over ground and about 61 – 67 dBA at five meters high over ground. This means that the measured values exceed the guideline values of approximately 8 dBA at two meters height and 12 dBA at 5 meters height according to BBR. For satisfactory sound levels to be obtained in Kopparlunden, several solutions need to be implemented such as an evacuation corridor between facades and apartments, increased distances between buildings and the noise source, noise screen and well proper placement and design of buildings.Samhällsbyggnadstekni
