| 4. | Also controls environmental noise . it requires aircrafts flying in and out of the hong kong international airport to be certified as meeting the most stringent noise standards
浏览详细内容亦包含管制环境噪音的规定，使所有在本港升降的飞机均须符合国际噪音标准。 |
| 5. | During the construction phase , the construction noise predicted at the representative noise sensitive receivers will not exceed the noise standard due to natural geographic shielding and the remoteness from the construction site
在施工阶段，由于自然地理的遮挡作用及这些敏感受体的位置远离工程地盘，所以建筑噪音预计将不会超过噪音水平。 |
| 6. | Sections 14 to 17 of the nco stipulates that it is an offence to manufacture , import , sell or hire a prescribed product if it is intended for use in hong kong and does not comply with noise standards set out in the regulations . it will also be an offence to use such a product
条例第14至17条订明，凡制造进口售卖或租赁指定产品准备供在本港使用，但产品并不符合规例所订的噪音标准，即属犯罪，使用这类产品亦属违法。 |
| 7. | A novel method for multi - scale denoising based on wavelet transform is given in chapter 2 . the new method improves the threshold - processing algorithm and present the form of white noise standard deviation at each scale . simulations show that while getting rid of noise mostly , this algorithm keeps the main edges of signal well
该算法对常规阈值方法进行了改进，给出了各尺度上噪声方差的计算公式，对多个非平稳信号消噪问题进行了对比仿真研究，仿真结果表明该算法不但能进一步提高非平稳信号的消噪精度，而且能保留信号主要细节。 |
