The headphone impedance plot is a measure of the dynamic resistance in ohms of the headphones over the entire audible frequency range.

耳机阻抗剧情是动态抵抗的措施在耳机的欧姆在整个可听见的频率范围。

We then calculate the difference between the two measurements and generate a numerical factor of how much noise attenuation the headphones are providing over the entire audible frequency range.

我们然后计算二次测量之间的区别并且引起多少噪声衰减一个数字因素耳机提供在整个可听见的频率范围。

L. f. noise can be better attenuated so as to obtain good attenuation characteristics over the entire audible frequency range by using active noise reduction technique in the closed-air type earmuff.

在密闭型耳罩中，利用有源降噪技术可以较好地衰减低频噪声以使整个可听声频率范围内获得良好的衰减特性。
