声谱仪是一种波分析仪,它产生一种永久的视觉记录,显示能量在频率和时间上的分布。本文介绍了该装置的工作原理,并给出了具体型号的机械结构和电路。讨论了在这种类型的分析中遇到的一些问题,特别是在诸如语音这样的复杂波中处理和描绘大范围分量电平的必要性所引起的问题。声谱图显示了各种各样的声音,包括人声、动物和鸟类的声音、音乐、频率调制和杂音
The sound spectrograph is a wave analyzer which produces a permanent visual record showing the distribution of energy in both frequency and time. This paper describes the operation of this device, and shows the mechanical arrangements and the electrical circuits in a particular model. Some of the problems encountered in this type of analysis are discussed, particularly those arising from the necessity for handling and portraying a wide range of component levels in a complex wave such as speech. Spectrograms are shown for a wide variety of sounds, in- cluding voice sounds, animal and bird sounds, music, frequency modulations, and miscellaneous
