A New Method For Ecoacoustics? Toward The Extraction And Evaluation Of Ecologically-Meaningful Soundscape Components Using Sparse Coding Methods, Alice Eldridge, Michael Casey, Paola Moscoso, Mika Peck

Dartmouth Scholarship

Passive acoustic monitoring is emerging as a promising non-invasive proxy for ecological complexity with potential as a tool for remote assessment and monitoring (Sueur & Farina, 2015). Rather than attempting to recognise species-specific calls, either manually or automatically, there is a growing interest in evaluating the global acoustic environment. Positioned within the conceptual framework of ecoacoustics, a growing number of indices have been proposed which aim to capture community- level dynamics by (e.g., Pieretti, Farina & Morri, 2011; Farina, 2014; Sueur et al.,2008b) by providing statistical summaries of the frequency or time domain signal. Although promising, the ecological relevance and …
