摘要

多麦克风录音为录制的音频添加了空间信息,在生态系统监测中得到了新的应用。具体来说,在空间中放置声音可以提高动物计数的准确性,定位伐木和偷猎等非法活动,跟踪动物以监测其行为和栖息地的使用情况,并允许 "波束成形 "以放大来自目标方向的声音,从而进行下游分类。研究表明,空间声学具有许多优势,但由于设备通常昂贵、复杂、难以使用或只适合短期部署,因此其应用仍然有限。为了提高吸收率和可用性,我们提出了一种低成本、开源的六通道记录仪,完全采用市场上可买到的部件,可集成到太阳能供电的在线系统中。MAARU(多通道声学自主记录单元)在长期自主、被动和/或短期部署中作为一个独立节点工作。在此,我们将介绍 MAARU 的硬件和软件,并展示实验室和现场测试的结果,以调查该设备的耐用性和可用性。MAARU 可记录多声道音频,其成本和功耗要求与同类全向录音机相似。我们已经在英国和巴西部署了 MAARU 设备,结果表明 MAARU 能够准确定位 6 kHz 以下的纯音和 8 m 远的鸟叫声(±10° 范围内,分别为信号的 100% 和 >60%)。更大音量的鸟叫声的探测半径可能更远。我们还展示了波束成形如何与 MAARU 配合使用,以提高物种识别置信度得分。对于那些希望使用单个设备准确、轻松地探索空间声学的人来说,MAARU 是一种方便、低成本的选择,而且无需与建立阵列相关的高昂费用和复杂的处理过程。最终,MAARU 提供的多通道记录增加了方向性元素,可以增强对声学环境的记录,进一步推动空间声学在更广泛领域的应用。

期刊介绍: A British Ecological Society journal, Methods in Ecology and Evolution (MEE) promotes the development of new methods in ecology and evolution, and facilitates their dissemination and uptake by the research community. MEE brings together papers from previously disparate sub-disciplines to provide a single forum for tracking methodological developments in all areas. MEE publishes methodological papers in any area of ecology and evolution, including: -Phylogenetic analysis -Statistical methods -Conservation & management -Theoretical methods -Practical methods, including lab and field -This list is not exhaustive, and we welcome enquiries about possible submissions. Methods are defined in the widest terms and may be analytical, practical or conceptual. A primary aim of the journal is to maximise the uptake of techniques by the community. We recognise that a major stumbling block in the uptake and application of new methods is the accessibility of methods. For example, users may need computer code, example applications or demonstrations of methods.
