Outline of Final Research Achievements

A purpose of this study is the improvement of the floor impact sound prediction precision in consideration of flanking transmission. The floor impact sound insulations according to floor section specifications were arranged from the investigation about the timber building. In addition, the experiment for CLT panels was carried out, and it was confirmed that a damping material between a floor and a wall was effective for floor impact sound insulation for the emission sound reduction from the walls. Besides, the experiment with the 3-story CLT model building was carried out, and it was confirmed that the effects of damping material, floating floor and suspended ceiling. Not only predictive precision of the floor impact sound insulation was improved, but also that the improvement floor impact sound insulation was enabled by considering flanking transmission loss from the above results.
