安全收听设备/系统导则 |
 |
ITU-T H.870建议书描述了对安全收听设备和系统即个人/便携式音频系统,尤其是那些用于播放音乐的系统的要求,以保护人们免受听力损失。本建议书还提供了一个术语表,以便人们就声音,听力和听力损失的理解和背景信息达成共识。本建议书推荐了避免不安全收听的标准:其中一种适用于成人,另一种适用于儿童,两者均基于等能量原则,即假设等量的声音能量将导致等量的声音引发永久性阈值移动,而不管能量在时间上的分布如何。重要的是,本建议书提供了关于安全收听的健康通信导则,以便在必要时可以有效地传递适当的警告信息。这类信息的例子见附录七。最后,本建议书还提供了有关剂量测定的实施和相关问题的信息。通信设备和辅助设备不属于本建议书的范围。游戏设备亦是未来的研究方向。该标准由世界卫生组织(WHO)和国际电信联盟(ITU)在“安全收听”举措下共同制定,并已被两个组织采用。 |
