安全收听设备/系统导则 |
 |
ITU-T H.870建议书描述了安全音响设备和系统的要求,被称作个人/便携式音响系统,尤其指音乐播放设备,以保护人们免受听力损伤。此外,建议书还提供了用于共同理解和说明声音、听力及听力损伤的背景信息的词汇表。
建议书还为避免不安全音响推荐了标准:基于等能量原则,推荐了一条成人标准和一条儿童标准,假设等量的声能量将导致等量的声音引起的永久阈值偏移,而不管能量随时间的分布。
重要的是,本建议书还为安全音响提供了健康传播导则,能够使必要情况下的警示消息得到有效传播。警示消息示例见附录VII。最后,本建议书还对剂量测定的实施和相关问题做了解释。本建议书不包过通信设备和辅助设备,游戏设备也需进一步研究。 |
