Rats appear largely silent to us, but they make many sounds beyond the human hearing range. These are termed ultrasonic vocalizations and are probably used for communication. By using specialized equipment, it is possible to eavesdrop on these inaudible calls. In this way, we have been able to discern more than a dozen types of vocalizations. Different kinds of vocalization are prevalent in different situations, suggesting that they may reflect different emotional states. For example, some evidence suggests that certain kinds of vocalization might indicate when a rat is experiencing positive emotion.

对我们来说，老鼠基本上是沉默的，但它们发出的许多声音超出了人类的听力范围。这些被称为超声波发声，可能用于交流。通过使用专门的设备，可以窃听这些听不见的电话。通过这种方式，我们已经能够分辨出十几种发声方式。不同的发声方式在不同的情况下普遍存在，这表明它们可能反映了不同的情绪状态。例如，一些证据表明，某些类型的发声可能表明一只老鼠正在经历积极的情绪。
