ActiveElectroacoustics—Methods to determine corrections to obtain the free-field response of a sound level meter
电声学 确定声级计自由场响应修正值的方法
Application Summary AI generated
This standard specifies methods for calculating corrections to convert the measured response of a sound level meter under diffuse-field or pressure-field conditions to its equivalent free-field response. It is applied in the calibration and type testing of sound level meters, ensuring accurate sound pressure level measurements in environments like open-air noise monitoring or anechoic chambers. The standard is essential for manufacturers, metrology laboratories, and acoustical engineers to achieve standardized, comparable acoustic measurements across different testing contexts.
