Humans often express themselves through unconventional vocalizations such as high-pitched whining noises. These vocal outbursts are not dissimilar to the sounds made by a wounded animal, and they convey a similar sense of distress or urgency. In fact, human emotional expression can sometimes border on the irrational. People may become agitated or even hysterical in certain situations, resulting in verbal or physical behavior that is entirely uncoordinated and chaotic.
