The noise signal of passing car is gathered through microphone array, and processed off line with array signal processing theory, thus traffic volume and up and down vehicles can be estimated accurately
對麥克風陣列所採集車輛通過的聲頻信號，運用陣列信號處理理論進行離線處理，可以較準確地估計交通流量和上下行車輛數目。 -
The noise signal of passing vehicles is gathered with microphone array, and processed off line with the method of wide - band array signal processing, then the estimation of vehicle numbers can be transformed into the estimation of signal source numbers, up and down of the vehicle can be transformed into doa estimation of array signal processing. at the same time, vehicle types are classified using pca method of the pattern recognition based on vehicle noise, and some primarily study is done for vehicle recognition. at last, the result of the experiment proves this method is feasible
對麥克風陣列所採集的車輛行駛時的聲音信號，運用寬帶陣列信號處理的方法進行離線處理，並將車輛個數的估計轉化為陣列信號處理中信號源個數的估計，將車輛上下行的估計轉化為陣列信號處理中波達方向變化的估計，進而較準確地估計出了車輛的個數與行車方向；同時對所採集的車輛聲音信號應用模式識別中的主分量分析法實現了車輛的簡單分類，為實現車型識別作了一些初步的探索。 -
On experiencing some microphone feedback while introducing a song ) “ this next song is called … line noise. isn ' t it beautiful
（一邊測試麥克風，一邊介紹歌曲） 「接下來的這首歌是… … （傳來一陣噪音） ，是不是很好聽？ 」
