摘要
将大熊猫和家狗的吠叫声“旺”分别进行了频谱分析，大熊猫语图在４ｋＨｚ内由８条共振带重叠构成，共振带宽、长，边界清晰。大熊猫叫声“旺”的基颇为２００～３００Ｈｚ，次频带为４００Ｈｚ左右，叫声的幅度直方图似伽玛分布。家狗吠声“旺”的语图共振带短，埋于湍流乱纹中，家狗吠叫声中含很强的噪声，家狗叫声“旺”的基频为 ４００～ ５００ Ｈｚ，次频带为９００Ｈｚ左右，叫声的幅度直方图似高斯分布。
The frequency spectra of Panda's and Dog's bark are respectively analyzed, Panda's voice spectrum within 0-4kHz consists of 8 Overlapped broad and long resonance bands with sharp edges. The fundamental frequency of Panda's voice is within 200-300 Hz, the second harmonic band of it is about 400 Ha, and the amplitude histogram of Panda's bark is similar to γ-distribution. But in the voice spectrum of Dog's bark, the resonance bands are shorter and submerged in chaotic ripples, and there is a stronger noise of turbulent flow in Dog's barks. The fundamental frequency of a Dog's bark is within 400-500 Hz, the second harmonic band of it is similar to Gauss distribution.
