visible noise的意思|示意

The analysis of the (improved) structure shows that the increase of natural vibration frequency is visible, the vibration noise of the shield is suppressed distinctly.

改进后的分析结果表明排气二分管罩的自振频率明显提高，振动噪声得到有效抑制。

As you can see from the graphs and images on the noise page of this review the A77 is unequivocally noisier than its competitors both in terms of measured and visible noise.

正如你从本次评测的噪音页上的图形和图像中看到那样，无论是测量的噪点还是可见的噪点，A77确凿无误地比其竞争对手更多。

Meanwhile, some noises are added into frequency bands where it is less visible in order to achieve noise smooth of overall reconstructing image.

同时，在不灵敏频带内(如图象边缘区)引入一定噪声以达到整个恢复图象的噪声平滑。
