《GB/T 21228.1-2007声学表面声散射特性第1部分：混响室中无规入射声散射系数测量》由TC17（全国声学标准化技术委员会）归口，主管部门为中国科学院。
本标准规定了由表面粗糙度引起的表面无规入射声散射系数的测量方法。应在混响室中以足尺模型或实物缩尺模型进行测量。测量结果可用来描述有多少来自表面的声反射偏离了镜面反射。其结果还可用于与室内声学和噪声控制有关的对比和设计计算。本方法不适用于表征表面声散射的空间均匀分布特性。

Scope

This part of GB/T 21228 specifies the method for measuring the scattering coefficient of surface random incident sound caused by surface roughness. Measurements shall be made on full-scale or life-scale models in a reverberation chamber. The measurement can be used to describe how much the acoustic reflection from the surface deviates from the specular reflection. The results can also be used for comparison and design calculations related to room acoustics and noise control. This method is not suitable for characterizing the spatially uniform distribution characteristics of surface acoustic scattering.
