Abstract [en]

This thesis investigates and design innovative concepts of noise protection solutions (NPS) for the Swedish high-speed railway (HSR) that is planned to be built between Stockholm and Gothenburg in the near future. The planned traffic will start in 2035. The concepts have been developed through a design process, starting with a research phase of existing solutions for the problem, theory about noise and absorbing materials. Following by an analysis of all researched data to narrow down the project and the interviews with the Swedish transport administration, this in order to pinpoint the requirements for the NPS. To get opinions from people who are exposed to low frequency noise, two questionnaires were conducted with a total of 80 respondents. Because of the difficulty to find the exact target group of people who are only exposed to the noise from high speed trains, the first questionnaire was open for all people who are exposed to low frequency noise (traffic noise). The second questionnaire was published at Trafikverket Facebook page, and because of their high number of followers, people who are exposed to train noise could easily be reached. From the answers and the analyzed data, a requirement specification for the NPS was created with all the requirements that the NPS needed to have according to Trafikverkets standards and from the questionnaire. These requirements were the prerequisite used in the synthesis phase. Different brainstorming methods were used to develop a large amount of ideas. A workshop with people from the society was held to keep the creativity alive. From the first synthesis phase, six ideas out of 160 ideas were chosen by a dot evaluation, and in order to narrow down the ideas even more, a matrix evaluation was used. The matrix was built from the requirement specification to verify which ideas fit most of the requirements for a new NPS. From this evaluation, two concepts were chosen to be developed further. After a validation from Trafikverket, the two concepts were further developed, this by an open brainstorming session. Via discussions and sketching, new ideas for the concepts arose. We found solutions for the problems that arose with each concept and made final decisions about the design and material. Three concepts were 3D visualized in the CAD program Rhinoceros. Final touches of the concepts were made in Keyshot. Throughout this thesis, three concepts for noise protections for the HSR have been developed and the research question “How can innovation be created by using a design process?” have been discussed and answered.
