ActiveAcoustics--Hearing protectors--Part 1:Subjective method for the measurement of sound attenuation
声学 护听器 第1部分:声衰减测量的主观方法
Application Summary AI generated
This standard specifies a subjective method for measuring the sound attenuation of hearing protectors, such as earplugs and earmuffs. It is applied in industrial and occupational safety contexts to evaluate the real-world noise reduction performance of hearing protection devices worn by workers in noisy environments. The method relies on human test subjects to determine the attenuation values, ensuring the protectors meet regulatory requirements for hearing conservation programs.
