The headphone impedance plot is a measure of the dynamic resistance in ohms of the headphones over the entire audiblefrequency 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 audiblefrequency 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 audiblefrequency range by using active noise reduction technique in the closed-air type earmuff.
