Acoustic Indices for Eooacoustic Analysis

<your subtitle>

Development of long duration recordings a soundscape scale has encouraged emergence of acoustic indices. Acoustic indices are statistical summaries of sound characteristics, such as frequency, amplitudes, waveforms, intensity, to characterize changes of sound in an environment (Towsey et al., 2014; Fuller, Axel, Tucker, & Gage, 2015). Acoustic indices has adapted concepts from biodiversity indices, applying them and giving rise to acoustic diversity. In classical biodiversity indices, the units measured are species. In acoustic diversity, acoustic indices measure either intensity or loudness, complexity in sound, and soundscape elements (Sueur, Farina, Gasc, Pieretti, & Pavoine, 2014) .
