lovebird
Examples
- There were a series of special acoustic changes in budgerigar and psittacula agapornis " vocal after the section of nxiits
亚鸣禽虎皮鹦鹉及牡丹鹦鹉在断nxllts后其叫声的声学特性出现了一些特殊的变化。 - 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
本实验以非鸣禽(家鸽、家鸡) ，亚鸣禽(虎皮鹦鹉、牡丹鹦鹉)以及鸣禽(栗? )为实验材料，记录其正常叫声以及亚鸣禽断nxiits后的叫声，用cooledit2000声音处理软件制出原始信号及其展开图，声图，频率谱图以及能量统计分布图，并对所得结果进行声学比较分析，以期得到鸣禽、亚鸣禽及非鸣禽叫声在声学特性上的差异，以及亚鸣禽在断神经后叫声的声学变化，旨在为进一步解释其发声机制提供帮助。 - 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
牡丹鹦鹉在断右侧nxllts后其声图中音调上升支消失，因而其叫声变为以降音调为主的降调叫声；在断左侧nxllts后的声图中，其基本音以上的谐波成分减弱或消失而在断双侧神经后其声图表现为一系列具有较低基频的宽带谐波谱。
