The results of the ethological-bioacoustic study carried out in 18 male domestic cats are presented in this work. Facial gesture, postural, and acoustic activity was recorded. The dynamics of frequency characteristics of sound calls was studied by means of parametric analysis, the functional significance of the recorded vocalizations was determined in the process of development of conflict situations. The results obtained indicate the relationship between the emotional state and the dynamics of the spectral characteristics of the sound calls. It was shown that the absolute value of the first dominant frequency and signal duration reflect the excitation level of mates. A conclusion was drawn that the redistribution of power from the first to the second spectral peak is an informative sign reflecting the motivation change in the dominant male (from threat to attack).
本文展示了对18只雄性家猫进行的行为学-生物声学研究结果。记录了面部姿态、姿势及声学活动。通过参数分析研究了声音叫声频率特征的动态变化，在冲突情境发展过程中确定了所记录发声的功能意义。所得结果表明情绪状态与声音叫声频谱特征动态变化之间存在关联。结果显示，第一主导频率的绝对值和信号持续时间反映了同伴的兴奋程度。得出的结论是，功率从第一个频谱峰值重新分配到第二个频谱峰值是一个反映主导雄性动机变化（从威胁到攻击）的信息性标志。
