Acoustics—Sound-scattering properties of surfaces Part 1:Measurement of the random-incidence scattering coefficient in a reverberation room
IDT ISO 17497-1:2004
全国声学标准化技术委员会(SAC/TC 17)
GB/T 21228的本部分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。
