GB/T 25079-2010 Acoustics—Application of new measurement methods in building and room acoustics—MLS and SS methods
Basic Information
Scope
This standard specifies the application guidelines and requirements for the new method of measuring the acoustic characteristics of buildings and building components. It also provides guidelines and requirements for the selection of excitation signals, signal processing, and environmental control, as well as requirements for the linearity and time-invariance of the measured system.
This standard applies to the following measurements, such as the airborne sound insulation between rooms and external walls, the measurement of room reverberation time and other indoor acoustic parameters, the sound absorption in reverberation rooms, and the measurement of vibration level differences and loss factors.
The methods defined in this standard can replace the traditional methods defined in GB/T 19889 (all parts), ISO 3382 (all parts), and GB/T 212281.
