ActiveAcoustics--Hearing protectors--Part 2:Estimation of effective A-weighted sound pressure levels when hearing protectors are worn
声学 护听器 第2部分:戴护听器时有效的A计权声压级估算
Application Summary AI generated
This standard specifies a method for estimating the effective A-weighted sound pressure levels reaching a person's ear when hearing protectors, such as earplugs or earmuffs, are worn. It is applied in occupational noise exposure assessments and industrial hygiene contexts to evaluate the real-world attenuation of hearing protection devices, enabling safety professionals to predict noise reduction and ensure compliance with workplace hearing conservation regulations.
