摘要
本文介绍了护听器声衰减值的评价方法,对比了我国、ISO、欧洲EN、美国ANSI和澳大利亚新西兰AS/NZS标准中关于护听器声衰减值评价方法的差异。着重讨论在测试过程中,使用不同的受试者和护听器佩戴方式得出的检测数据与真实世界防护值的一致性情况。研究表明,使用"受试者自行佩戴"的方式测得的数据能更好地反映护听器在真实世界的防护性能。
This paper introduces the assessment method for acoustic attenuation value in guarding listening,and contrasts the difference in standards of our country,ISO,EN,ANSI and AS/NZS.It emphasizes the coherence between real protective value and testing data which is measured with different examinees in different adorn fashion.Research shows that measured data with wearing by oneself can reflect the real protective performance preferably.
