摘　　要：听力保护装置(hearing protection device,HPD)是保护听力不受环境噪声影响的最后一道防线,旨在将传导至耳蜗的噪声暴露剂量降低至安全阈限以下。本文介绍了听力保护装置的类型和衰减特性。并且结合听力保护装置的局限性,介绍了定制式听力保护装置和有源听力保护装置。听力保护装置的主要评估方法包括真耳阈值衰减法、真耳内置传声器法以及声学测试装置法。Hearing protection devices(HPD)are the last line of defense to protect hearing from environmental noise and are designed to reduce the exposure dose of noise transmitted to the cochlea below the safe threshold limit value.This paper introduces the types and attenuation characteristics of hearing protection devices.Combined with the limitations of hearing protection devices,the custom-fit hearing protection devices and Active Electronic hearing protection devices are introduced.The main assessment methods for hearing protection devices include:real-ear attenuation at threshold method,microphone in real-ear method,and acoustical test fixture method.
