Students and two teachers from the Oulu University of Applied Sciences (Oamk) visited DAS Kelo at the beginning of December 2021 to test the sound insulation properties of the building.

Both airborne sound insulation and impact sound insulation were measured. The former test measures how typical sounds, such as speech or music, is carried from one apartment to the next, while the latter measures how well sound from impacts, such as walking, travels between room spaces. A total of seven different test were carried out, and these included measuring sound traveling from one apartment to the next horizontally and vertically, and from the hallway to the apartments.

Apart from the initial measurement, all the values were within the limits set by the Finnish Ministry of the Environment, thus showing that sound insulation is not an issue in properly constructed wooden buildings. In addition to the measuring devices, an acoustic camera was also used. However, as the building was so well acoustically insulated, the use of the camera was rather redundant as it failed to show any major sound leaks.

DAS Kelo is located in Rovaniemi, Finland, and it is one of the demonstration buildings in the project. The building contains more than 100 student apartments, and it is made from prefabricated CLT elements.
