声学 建筑声学和室内声学中新测量方法的应用 MLS和SS方法
Application Summary AI generated
This standard specifies the application of Maximum Length Sequence (MLS) and Swept Sine (SS) measurement methods for determining acoustic parameters in buildings and rooms. It is used by acoustical engineers and testing laboratories to conduct impulse response measurements, enabling accurate evaluation of reverberation time, sound absorption, and sound insulation in spaces such as concert halls, offices, and auditoriums. The standard ensures consistent and reliable acoustic testing under controlled conditions, particularly where conventional methods may be impractical due to background noise or time constraints.
