ActiveAcoustics—Test methods for the qualification of free-field environments
声学 自由场环境评定测试方法
Application Summary AI generated
This standard specifies the test methods and evaluation criteria for qualifying free-field acoustic environments, such as anechoic chambers or open-air test sites. It is applied in acoustics metrology and product testing to ensure that sound pressure level measurements are free from reflections and background noise interference. Industries use it for calibrating microphones, testing loudspeakers, and validating noise emission measurements for equipment like household appliances or vehicles.
