标题： Test experiments with distributed acoustic sensing and hydrophone arrays for locating underwater sound sources

摘要： 鲸鱼和海豚依赖声音进行导航和交流，这使它们成为研究语言进化的一个引人入胜的主题。 传统的水听器阵列已被用于记录它们的声学行为，但光纤已成为一种有前途的替代方案。 本研究探讨了分布式声学传感（DAS）技术的使用，该技术检测光纤中的局部应力，用于水下声音记录。 在苏黎世湖进行了一项实验，部署了光纤电缆和自制的水听器阵列。 在不同位置播放测试信号，并将生成的数据同步并合并到文件中。 分析显示DAS通道具有不同的频率响应，并提供了关于湖中声音传播的见解。 识别了与电缆灵敏度、采样率和广播保真度相关的挑战。 此数据集为推进水下环境中的声学传感技术提供了宝贵的资源，特别是对于研究海洋哺乳动物的声音行为。 显示英文摘要

摘要： Whales and dolphins rely on sound for navigation and communication, making them an intriguing subject for studying language evolution. Traditional hydrophone arrays have been used to record their acoustic behavior, but optical fibers have emerged as a promising alternative. This study explores the use of distributed acoustic sensing (DAS), a technique that detects local stress in optical fibers, for underwater sound recording. An experiment was conducted in Lake Zurich, where a fiber-optic cable and a self-made hydrophone array were deployed. A test signal was broadcasted at various locations, and the resulting data was synchronized and consolidated into files. Analysis revealed distinct frequency responses in the DAS channels and provided insights into sound propagation in the lake. Challenges related to cable sensitivity, sample rate, and broadcast fidelity were identified. This dataset serves as a valuable resource for advancing acoustic sensing techniques in underwater environments, especially for studying marine mammal vocal behavior.
