To provide a sound absorption system that saves space and improves a sound absorption effect.SOLUTION: A sound absorption system according to one embodiment is a sound absorption system including: a first sound absorbing material including a first sound absorbing layer, a second sound absorbing layer, and a first segmental layer sandwiched between the first and second sound absorbing layers; and a second sound absorbing material including a third sound absorbing layer, a fourth sound absorbing layer, and a second segmental layer sandwiched between the third and fourth sound absorbing layers. The first sound absorbing material is disposed in contact with a first wall region of a first wall, the first sound absorbing layer is disposed between the first wall region and the first segmental layer, the second sound absorbing material is disposed in contact with a second wall region of a second wall intersecting the first wall by less than 180°, the third sound absorbing layer is disposed between the second wall region and the second segmental layer, the third wall region between the first wall region and the second wall region is separated from the first sound absorbing material and the second sound absorbing material, and the distance between the first sound absorbing material and the second sound absorbing material is less than thickness of either of the first sound absorbing material and the second sound absorbing material.SELECTED DRAWING: Figure 1 【課題】 省スペースで且つ吸音効果を向上した吸音システムを提供する。【解決手段】 一実施形態に係る吸音システムは、第１吸音層、第２吸音層、および第１吸音層と第２吸音層とに挟まれた第１区分層を含む第１吸音材と、第３吸音層、第４吸音層、および第３吸音層と第４吸音層とに挟まれた第２区分層を含む第２吸音材と、を含む吸音システムであって、第１吸音材が第１壁の第１壁領域に接して配置され、第１吸音層が第１壁領域と第１区分層との間に配置され、第２吸音材が第１壁と１８０°未満で交差する第２壁の第２壁領域に接して配置され、第３吸音層が第２壁領域と第２区分層との間に配置され、第１壁領域と第２壁領域との間の第３壁領域は、第１吸音材および第２吸音材から離隔し、第１吸音材と第２吸音材との間の距離が、第１吸音材および第２吸音材のいずれの厚さよりも小さい。【選択図】 図１
