There were a series of special acoustic changes in budgerigar and psittacula agapornis " vocal after the section of nxiits
亞鳴禽虎皮鸚鵡及牡丹鸚鵡在斷nxllts后其叫聲的聲學特性出現了一些特殊的變化。Psittacula agapornis ), oscine passenon ( emberiza rutila ) and the vocalizations of sub - oscine passerine ( melopsittacus undulates, psittacula agapornis ) after sectioning nxiits were recorded by sharp gf - 6060 recorder. cooledit2000, an acoustic analyzing software, was used to produce the original wave and it ' s expanded time windows, sonograms, spectrums and power static histograms. to distinguish the acoustic differences of their natural vocal and to find the changes of sub - oscine passerine ' s song after sectioning nxiits, the above results is acoustically analyzed and compared, expecting to provide some advantage to further explaining the mechanism of vocal production
本實驗以非鳴禽（家鴿、家雞） ，亞鳴禽（虎皮鸚鵡、牡丹鸚鵡）以及鳴禽（栗? ）為實驗材料，記錄其正常叫聲以及亞鳴禽斷nxiits后的叫聲，用cooledit2000聲音處理軟體制出原始信號及其展開圖，聲圖，頻率譜圖以及能量統計分布圖，並對所得結果進行聲學比較分析，以期得到鳴禽、亞鳴禽及非鳴禽叫聲在聲學特性上的差異，以及亞鳴禽在斷神經后叫聲的聲學變化，旨在為進一步解釋其發聲機制提供幫助。In the sonograms of psittacula agapornis after the section of right side nxiits the ascending parts of the tone disappeared. this causes their vocalizations became the descendent - call. and in the sonograms with the left side nxiits sectioned, the harmonic parts above the basic song were weaken or disappeared
