现有的关于大象声学交流的知识主要基于非洲物种(非洲斑齿象和环齿象)。对亚洲象(Eephas Max)的交流研究相对较少。为了对口鼻目动物声音交流的进化和功能的理解提供依据，我对野生亚洲象的声音交流进行了定量描述。我根据声音特征将叫声分为8种“单一”叫声、5种“组合”叫声和一种可能独特的雄性叫声，总共至少有14种不同的叫声类型。其中一些发声以前从未被描述过。某些低频呼叫是单独不同的。声音信号存在于广泛的社会背景中，不同年龄和性别的人在呼叫产生方面存在一些差异。
Existing knowledge of acoustic communication in elephants is based primarily on African species (Loxodonta africana and Loxodonta cyclotis). There has been comparatively less study of communication in Asian elephants (Elephas maximus). In order to provide a basis for understanding the evolution and function of acoustic communication in proboscideans, I present a quantitative description of vocal communication in wild Asian elephants. I classify calls by acoustic features into 8 'single' calls, 5 'combination' calls and one possibly unique male call for a total of at least 14 distinct call types. Some of these vocalizations have never before been described. Certain low-frequency calls are individually distinct. Acoustic signals occur in a wide range of social contexts, with some differences in call production among age and sex classes.
