1) thedash of oars striking the water
划桨击水的声音
2) The act of paddling.
划桨划桨的动作
4) An oar skimming the surface of the pond.
划过池塘水面的桨
5) piling sound
锤击声音
1.
On the basis of the analysis of fast Fourier transform and some basic statistical variables,the piling sound is analyzed in frequency domain;then the character,mean absolute deviation,and corresponding parameters on the piling sound recognition are acquired;thus an algorithm can be developed to count the number of piling sound by rule and line.
针对常规人工记录锤击数的低效情况,在此将打桩现场采集的声音信号运用快速傅立叶变换到频率域,对频谱进行多个统计量的分析,并同时考虑了锤击声音可能受到附近噪音的干扰,从中选取平均绝对值偏差这个统计量作为识别锤击次数的特征,由此探测得到一组可以较为精确识别锤击数目的特征参数,实现了锤击数准确识别的自动化。
2.
A digital system,which is used to recognize the number of piling sound,is firstly put forward.
继而在考虑锤击声音可能受到附近噪音污染的情况下,确定出一组精确识别锤击次数的参数。
6) metallic sound
金属撞击似的声音
