哺乳动物对声音信号的感知和识别是基于听觉能力的，听觉能力具有物种特有的特征，但在听觉系统中共享共同的声音处理机制。哺乳动物的常见感知能力指的是听力图值，即对声音的频率、强度和持续时间的感知上的显著差异，以及听力中频谱和时间分辨率的机制和极限。在讨论了这些关键特征之后，我们将展示哺乳动物听觉系统中的知觉界限和知觉类别之间的边界如何在评估声音信息的基本生物学意义时变得有效。最后，我们将简要介绍由于学习发声中细微差异的能力而导致的声音识别，以便将发声动物识别为特定物种和/或个体的一部分。
Perception and recognition of vocal signals in mammals is based on hearing abilities, which have a species-specific profile but share common mechanisms of sound processing in the auditory system. Common perceptual abilities in mammals refer to audiogram values, just noticeable differences in the perception of frequencies, intensities and duration of sounds, and to the mechanisms and limits of spectral and temporal resolution in hearing. After the discussion of these key features, we will show how perceptual limits and borders between perceptual classes in the auditory systems of mammals become effective in assessing the basic biological meaning of vocal messages. Finally, we will briefly address sound recognition as a consequence of the ability to learn subtle differences in vocalizations in order to identify the vocalizing animal as a member of a certain species and/or as an individual.
