三、主要指标及项目内容Main indicators and project contents

1、当外部环境噪声：Len（A）≤65dB（A），周围无异常干扰（如砸 地、打桩、冲击)且空调通风系统关闭，仅灯具开启时，半消声室室内本底噪声：Lgn(A)≤20dB（A）。

When the external environmental noise: Len (A) ≤ 65dB (A), there is no abnormal interference around (such as smashing the ground, piling, impact) and the air conditioning and ventilation system is turned off, and only the lamps are turned on, the indoor noise floor of the semi-anechoic chamber: Lgn(A)≤20dB(A).

2、截止频率: Fc≤100Hz。

Cut-off frequency: Fc≤100Hz.
