大鼠在种内通信中使用的超声波呼叫具有声学特征，其可以被接收者选择性地识别，并且具有反映发送者响应的大小的定量维度。本文综述了动物交流的基本原理，特别是大鼠的叫声，以及超声叫声的特征，这些特征可以反映这种定量方面。幼鼠的隔离叫声在频率和持续时间上各不相同，并且随着时间的推移具有变化的超声结构。据推测，大坝的定量“信息”不仅编码在呼叫的数量，但也在频率扫描。成人的22 kHz报警电话的特点是一个相对恒定的声音频率，边际频率调制，并在呼叫持续时间显着的变化。据推测，这些呼叫的数量方面可能编码在呼叫长度。最后，50 kHz的呼叫，这是在食欲行为发出的成年人是非常短的呼叫，具有相对恒定的呼叫持续时间，和可变的声音频率。据推测，峰值频率以及每时间单位的呼叫数反映了50 kHz呼叫的定量方面。
Ultrasonic calls used by rats during intraspecies communication have acoustic features, which can be selectively recognized by recipients, and possess a quantitative dimension reflecting the magnitude of the senders-response. This paper reviews basic principles of animal communication with particular attention to rat calls, and the features of ultrasonic calls, which could reflect such a quantitative aspect. Isolation calls of rat pups vary in frequency and duration and have changing sonographic structure over time. It is hypothesized that the quantitative "message" for the dam is encoded not only in the number of calls but also in frequency sweeps. The 22-kHz alarm calls of adults are characterized by a relatively constant sound frequency, marginal frequency modulation, and remarkable variability in call duration. It is hypothesized that quantitative aspect of these calls may be encoded in call length. Finally, the 50-kHz calls of adults, which are emitted in appetitive behavior are very short calls, with a relatively constant call duration, and a variable sound frequency. It is hypothesized that the peak frequency as well as the number of calls per time unit reflect the quantitative aspect in 50-kHz calls.
