声学记录已被确认为非侵入性监测海洋环境的宝贵工具，是对传统目视调查的补充。迄今为止，对珊瑚生态系统进行的声学调查仅限于堡礁和浅水区（10-30米）。由于它们可能为珊瑚礁生物提供避难所，因此监测外礁斜坡和描述深层环境的音景可以提供对珊瑚生态系统不同生境特征的深入了解。在这项研究中，声学功能的四个不同的栖息地，不同的地形和基板，位于不同的深度从10至100米，记录在白天的外礁坡的北部海岸的莫雷阿岛（法属波利尼西亚）。大堡礁似乎是最嘈杂的栖息地，而在其他栖息地的平均声级下降与他们的距离，从珊瑚礁和深度增加。然而，声音水平高于预期的传播模型，支持这些栖息地拥有自己的声源。虽然珊瑚礁的声音可以吸引海洋幼虫，但来自更深栖息地的声音也可能具有不可忽视的吸引力，在珊瑚礁本身之前发挥作用。
Acoustic recording has been recognized as a valuable tool for non-intrusive monitoring of the marine environment, complementing traditional visual surveys. Acoustic surveys conducted on coral ecosystems have so far been restricted to barrier reefs and to shallow depths (10–30 m). Since they may provide refuge for coral reef organisms, the monitoring of outer reef slopes and describing of the soundscapes of deeper environment could provide insights into the characteristics of different biotopes of coral ecosystems. In this study, the acoustic features of four different habitats, with different topographies and substrates, located at different depths from 10 to 100 m, were recorded during day-time on the outer reef slope of the north Coast of Moorea Island (French Polynesia). Barrier reefs appeared to be the noisiest habitats whereas the average sound levels at other habitats decreased with their distance from the reef and with increasing depth. However, sound levels were higher than expected by propagation models, supporting that these habitats possess their own sound sources. While reef sounds are known to attract marine larvae, sounds from deeper habitats may then also have a non-negligible attractive potential, coming into play before the reef itself.
