This report's aim is that by field measurements determine the function of Aprobo soundproofing material dB2 for reducing impact sounds, the measurements is done in ?the school for fine art? in Umeå also known as ?konstnärligt campus building nine?. The construction technique is used in areas sensitive to impact sound between different floors in the building. The measurement?s is also to do a function control of the buildings sound quality compared to Swedish and European standard when it comes to air sound, impact sound and reverberation time . The report have concluded that the function of Aprobo dB2 as an impact isolation is correct but that it have no positive result on the air sound isolation in nether horizontally or vertically when controlled in weighted values. The report?s conclusions can be used in future projections of buildings that suffer from impact sensitivity in vertical direction, it can also be used to project for impact sound isolation in horizontal direction but that it is important to choose the proper construction above the isolation for that to work.
