虽然马蹄形蝙蝠的回声定位已经得到了很好的研究，但实际上对它们的通信呼叫的特征和功能一无所知。因此，一组圈养的成年大马蹄蝙蝠产生的通信呼叫记录在各种社会互动的自由飞行设施。分析表明，这一物种表现出惊人的丰富的声乐曲目不同的许多spectrotemporal方面。叫声分为17个音节类型（10个简单音节和7个复合音节）。音节组合成六种简单短语和四种组合短语。大多数音节的持续时间超过100毫秒，具有多个谐波和基本频率，通常超过20 kHz，尽管其中一些人也能听到。初步的行为观察表明，许多叫声是在与同种动物直接互动和响应同种动物的社交叫声时发出的，而不需要身体接触。一些类似回声定位的发声也显然起到了沟通的作用。这些结果不仅揭示了一个迄今为止被广泛忽视的马蹄形蝙蝠发声方面，但也提供了基础，为未来的研究的神经控制生产的交流发声的回声定位脉冲序列的生产。
Whereas echolocation in horseshoe bats is well studied, virtually nothing is known about characteristics and function of their communication calls. Therefore, the communication calls produced by a group of captive adult greater horseshoe bats were recorded during various social interactions in a free-flight facility. Analysis revealed that this species exhibited an amazingly rich repertoire of vocalizations varying in numerous spectrotemporal aspects. Calls were classified into 17 syllable types (ten simple syllables and seven composites). Syllables were combined into six types of simple phrases and four combination phrases. The majority of syllables had durations of more than 100 ms with multiple harmonics and fundamental frequencies usually above 20 kHz, although some of them were also audible to humans. Preliminary behavioral observations indicated that many calls were emitted during direct interaction with and in response to social calls from conspecifics without requiring physical contact. Some echolocation-like vocalizations also appeared to clearly serve a communication role. These results not only shed light upon a so far widely neglected aspect of horseshoe bat vocalizations, but also provide the basis for future studies on the neural control of the production of communicative vocalizations in contrast to the production of echolocation pulse sequences.
