残留噪声 meaning in English

residual noise

In practical application , due to the parameter accuracy of two point temperature correction is limited by readout circuit noise 、 dynamic range 、 analogue to digital converter word length and calculating noise , the performance of focal plane array detector is not the performance it should be
目前实用性较好的两点温度定标法的校准系数精度受读出噪声、信号动态范围、模数转换字长和运算噪声的限制，很难使焦平面探测器的空间残留噪声达到应有的精度。
In order to reduce the musical residual noise and the background noise , a speech enhancement method based on masking properties of the human auditory system is described . this method uses bark wavelet packet transform to simulate the frequency feature of human auditory model to get the threshold
本文以最大限度减少残留噪声和背景噪声为目的，采用bark子波分析的方法模拟人耳基底膜的频率分析特性来进行语音增强，重点进行模拟人耳听觉掩蔽效应来确定除噪阈值的研究。
