1) signal-to-mask ratio; signal-to-noise ratio
信号噪声比<声>
2) signal-to-noise ratio
信号噪声比
1.
To increase signal-to-noise ratio(SNR) of medical ultrasound image,a frequency-modulated(FM) ultrasound transmitted imaging method is developed,where a weighted linear FM ultrasound is transmitted to enhance the emission energy without increasing the emission ultrasound pressure,and the image signal is formed by the demodulated ultrasound.
为了提高医学超声图像的信号噪声比,研究了调频超声发射的成像方法。
3) signal to noise ratio(SNR)
信号/噪声比
4) noise-signal ratio
噪声信号比
5) S/N (signal /noise ratio)
信号噪声比，信噪比
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。
