SOUND ABSORBING STRUCTURE AND METHOD OF INSTALLING THE SAME
PROBLEM TO BE SOLVED: To provide a sound absorbing structure capable of absorbing sound in various frequency ranges without losing design unity.SOLUTION: A sound absorbing structure makes use of Helmholtz resonators, and each resonator body member 20 includes partitioning wall members 29 for partitioning an internal space thereof. Each partitioning wall member 29 is an airtight material that is installed on a resonator body member 20 side to be in contact with a counter surface. At least one of the spaces partitioned by the partitioning wall members 29 becomes an acoustic chamber that functions as a Helmholtz resonator.SELECTED DRAWING: Figure 6
【課題】意匠の統一感を失うことなく様々な周波数域に対応して吸音が可能な吸音構造体を提供する。【解決手段】ヘルムホルツ共鳴器を利用した吸音構造体であって、共鳴器本体材２０の内部空間を区画するための隔壁材２９を備え、隔壁材２９は、共鳴器本体材２０側に取り付けられて対向面に接触する気密材であり、隔壁材２９により区画されたスペースのうちの少なくとも１つを、ヘルムホルツ共鳴器として機能する吸音室とした。【選択図】図６
