【摘要】 本文介绍了应用微型计算机,对猫叫声信号进行了短时平均幅度的分析和谱分析的方法,实际分析了“怒叫中枢”微量注射生长抑素对怒叫声信号幅度的影响;分析了怒叫声信号的时域和频域的特性,比较了刺激“怒叫中枢”的叫声与刺激中央灰质发音已叫声的异同。本文介绍的猫叫声信号的分析方法可作为研究猫发音机制的重要手段。更多还原

【Abstract】 The microcomputer system was used to process the call signals in cats. The short time mean amplitude and spectrum of cat groaning or growling were plotted. The characteristics of the range of time and frequency of thses singnals were investigated. Moreover, the decrease in amplitude of groaning was measured by the method of short time mean ampltiude after injection of micro dose of somatostatin into the "groaning center". It had also been shown that there were some differences in spectra of groaning or growling between the "groaning center" and periaqeductal grey matter. Experimental data suggested that the wave spectrum analysis would be a good method in study the mechanism of vocalization and emotion.更多还原
