声学景观或声景可因生物(“生物声”)、地球物理(“地球声”)和人为(“人类声”)组成部分而有所不同，在某些环境中，如许多珊瑚礁，生物声主导声景观。我们比较了42个地点3个不同时间段(白天、黄昏和夜晚)的126个声音记录，并同时进行了鱼类和栖息地调查，以调查声学参数与法属波利尼西亚甘比耶群岛珊瑚礁生物和物理特征的关系。主成分分析表明，声景观的大部分变异可以用4个因素来描述：(1)全带宽均方声压级(SPL；0.01kHzdBre1μPa.)；频率(2)SPL0.63 kHZ；(3)0.16-2.5kHZ之间；(4)拍虾的次数。记录中的抓拍次数和0.63 kHz以上的SPL与活珊瑚覆盖率、成鱼和幼鱼的密度和多样性呈负相关，而与死珊瑚覆盖率和一天中的时间(从白天到黄昏到夜间)呈正相关。全频带SPL和中频SPL与海况、深度、波利特珊瑚、珊瑚分枝形态和块状珊瑚以及海底是否被珊瑚覆盖(活的或死的)呈正相关。声景记录有助于更全面地评估生态景观，在后勤限制妨碍传统调查方法的情况下，被动声学监测可提供关于生境是否随时间变化的宝贵信息。
Acoustic landscapes, or soundscapes, can vary due to biological (‘biophony’), geophysical (‘geophony’) and anthropogenic (‘anthrophony’) components, and in some environments, such as many coral reefs, biophony dominates the soundscape. We compared 126 sound recordings from 3 different times of day (day, dusk and night) at 42 locations with concurrent fish and habitat surveys to investigate the relationships of acoustic parameters with biological and physical characteristics of coral reefs in the Gambier Archipelago, French Polynesia. Principal Component Analysis revealed that most of the variability in soundscapes could be described using only 4 factors: (1) full bandwidth root mean squared sound pressure level (SPL; 0.01 to 22.5 kHz in dB re 1 μPa); SPL of frequencies (2) >0.63 kHz and (3) between 0.16 and 2.5 kHz; and (4) the number of snaps made by snapping shrimp. Number of snaps in a recording and SPL above 0.63 kHz were negatively related to live coral cover, and the density and diversity of adult and juvenile fish, but positively related to dead coral cover and time of day (as the day progressed from day to dusk to night). Full bandwidth SPL and midrange SPL were positively related to sea state, depth, Porites coral, the coral forms ‘branched’ and ‘massive’ and whether the bottom was coverd by coral (live or dead). Soundscape recordings can contribute to a more complete assessment of ecological landscapes and, in cases where logistical constraints preclude traditional survey methods, passive acoustic monitoring may give valuable information on whether habitats are changing over time.
