1) Equivalent Noise Field
等效噪声场
2) noise equivalent magnetic field
等效噪声磁场
1.
Experimental results indicate that the noise equivalent magnetic field of this sensor to be distinguished is 10 -8 T/Hz,and the linearity of characteristic curve is better than 1% in measurement range form 0 T to 45×10 -4 T when the magnetic field signals are alternating ones.
实验结果表明,传感器可分辨的等效噪声磁场为10-8T/Hz,测量0~45×10-4T范围内的交变磁场时,传感器的线性度小于1%。
5) equivalent noise ratio
等效噪声比
6) equivalent noise pressure
等效噪声压
补充资料:噪声等效声级(简称LEQ)
噪声等效声级(简称LEQ):是指在规定的时间内,某一连续稳态声的A\[计权\]声压,具有与时变的噪声相同的均方A\[计权\]声压,则这一连续稳态声的声级,就是此时变噪声的等效声级。噪声等效声级(分贝)数值越小越好。
