摘　　要：介绍了封闭空间内几个基本声学特性,如简正振动模式、简正频率、简正振动频率分布、稳态频率响应等,所谓达到稳态就是声源的输出功率与室内的吸收功率达到平衡时,室内各点的声压级处于稳定值。特别说明了大房间与小房间的不同声学特性。Some of the basic acoustic characteristics in the closed space normal vibration modes, normal frequency, steady state frequency response, etc, are introduced. The differences of the acoustic characteristics of big room and small room are illustrated especially.

关 键 词：室内声学 稳态频率响应 简正振动模式 简正频率
