Recognition of piling sound on time-domain
Hui Wang · Engineering of Surveying and Mapping · 2008
A digital system,which is used to recognize the number of piling sound,is firstly put forward.Then,the maximum(a statistical variable) is proposed as the characteristic of piling sound.Based on some noise in sampling files are acquired to recognize the number of piling sound accurately,corresponding parameters are acquired. The result using above parameters to recognize the number of piling sound is better than analogous circuit's.
