GB/T 16404.2-1999 《Acoustics--Determination of sound power levels of noise sources using sound intensity--Part 2:Measurement by scanning》 Related products

GB/T 16404.2-1999 is a standard in the field of acoustics, focusing on the scanning Measurement mode in the measurement of noise source sound power level by sound intensity method. The standard clearly applies to all kinds of noise sources, elaborates the scanning Measurement principle based on the sound intensity principle, specifies the specific process of scanning measurement, such as measurement point layout rules, scanning path planning, sound intensity data collection and processing methods, etc., to provide operating specifications for the accurate measurement of noise source sound power level in complex acoustic environment, and to help acoustic research, noise pollution prevention and related Product Research & Development.
