| 摘 要： | 耦合空间广泛地存在于各类建筑中,具有复杂的声场特性。关于耦合空间已有的研究多是建立在扩散声场的基础上,应用统计理论给出近似的分析。本研究从波动声学出发,从简正频率的角度探讨了耦合空间的低频简正特性。

| Abstract: | The finite element method is used to study the normal modes distribution in coupled rooms. The effect of the joint area and the position of the opening on the normal modes are also discussed. It is shown that for the two rooms coupling each other through an opening, the normal mode of the over_ all enclosure has been selectively modified. |
