The research project AkuLite ended 30th April this year and AcuWood will finish the 30th of September and almost four years of acoustic research with a focus on acoustics and vibrations in multi-storey residential buildings with light weight structures terminates thereby. However this is not the same thing as all activity ceases in lightweight acoustic and vibration construction research. High activity has been undertaken during late 2012 and beginning of 2013 in order to set up projects that can continue after AkuLite and AcuWood. Despite great progress in both projects and a clearly elevated level of knowledge everything is, of course, not yet solved. However, the goals are fulfilled and now it is time to enter the next phase. AkuLite and AcuWood have both been an exciting journey with a great number of dedicated participants involved. The projects consisted of a total of ten institutions / research practitioners and about 35 to 45 different industries throughout Europe. The main focus for the projects were to deliver new proposals for evaluation measures regarding sound insulation in order to provide right target values for the construction industry when they develop new building systems for the future.
