A meta-analysis of the effects in alpha acoustic indices
Open accessAbstract
摘要: 通过声学指数量化声音的特征反映生物的组成和生境信息, 是一种高效率、低干扰的监测方式。该研究领域在近十多 年来得到了快速的发展, 不断有新的声学指数被提出, 同时也有大量的实证研究。声学指数可分为反映录音内信息的alpha声 学指数和比较不同录音之间差异的beta声学指数, 其中alpha声学指数的实证研究较多。本文在汇总已有研究数据的基础上进 行meta分析, 关注alpha声学指数与动物多样性、生境质量、动物活跃性之间关联的方向和程度。基于文献调研, 本文对8个 常用的声学指数进行了总结分析: 声学复杂度指数(acoustic complexity index, ACI)、声学熵指数(acoustic entropy index, H)、 生物声学指数(bioacoustic index, BI)、标准化声景差异指数(normalized difference soundscape index, NDSI)、声学多样性指数 (acoustic diversity index, ADI)、声学均匀度指数(acoustic evenness index, AEI)、声学丰富度指数(acoustic richness index, AR)和 频峰数(number of peaks, NP)。其中, ACI是使用频次最高的声学指数, 与动物多样性、生境质量和动物活跃性均存在正相关 的关系。ACI与陆地动物活跃性之间的联系最为密切, 总效应量的均值达到0.53。然而,其他声学指数与动物多样性、生境质 量和动物活跃性之间的关联程度普遍不高, 平均解释力不足10%。此外, AEI与生境质量呈显著负相关的关系(相关系数的均

The Acoustic Complexity Index (ACI) tracks how acoustic energy fluctuates over time and often correlates with species richness, habitat quality, and general animal activity.
“The Acoustic Complexity Index (ACI), for instance, tracks how acoustic energy fluctuates over time and often correlates nicely with species richness, habitat quality, and general animal activity”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
