ActiveAcoustics - Sound-scattering properties of surfaces - Part 1: Measurement of the random-incidence scattering coefficient in a reverberation room
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
Application Summary AI generated
This standard specifies a method for measuring the random-incidence scattering coefficient of surfaces in a reverberation room, quantifying how much sound energy is scattered versus reflected. It is applied in architectural acoustics and building material testing to evaluate the acoustic performance of wall panels, ceilings, and diffusers for room design and noise control.
