음향 — 청력측정설비 교정용 영점 기준 —제4부: 협대역 마스킹 잡음레벨 기준 声学 - 参考零用于测量设备的校准 - 第4部分:窄带屏蔽噪声的参考电平
发布日期: 2020-12-29
该标准对纯音测量中以耳机空气为媒介的传导时出现的窄带掩蔽噪声进行规定。数据表现为,当掩蔽耳机安装在适当的音响耦合器或耳模拟器或人工耳上时,KS I ISO 389-1或KS I ISO 389-2中明确规定的,在纯音频率上的基准等价域值声压标签上加上的项。数据应以1/3或1/2音带噪声给出。
이 표준은 순음 측정에서 이어폰으로부터의 공기를 매개로 하는 전도 시 나타나는 협대역 마스킹 잡음에 대해 규정한다. 데이터는 마스킹 이어폰이 적절한 음향 커플러나 귀 시뮬레이터 또는 인공 귀에 부착될 때, KS I ISO 389-1이나 KS I ISO 389-2에 명시되어 있는 대로 순음의 주파수에서의 기준 등가 역치 음압 레벨에 더해진 항으로 표현된다.데이터는 1/3이나 1/2 옥타브 밴드 잡음으로 주어야 한다.
