Bioacoustics Data Analysis – A Taxonomy, Survey and Open Challenges

Rama Rao Kvsn, James Montgomery, Saurabh Garg, Michael Charleston
2020 IEEE Access  
The survey first identifies common processing steps to analyse bioacoustics data. As bioacoustics monitoring has grown, so does the volume of raw acoustic data that must be processed.  ...  To help current researchers and identify research gaps, this paper aims to summarise and classify these works in the form of a taxonomy of the various bioacoustics applications and analysis approaches.  ...  general bioacoustics algorithms need to work in diverse and changing natural environments.  ...

Adaptation of brain regions to habitat complexity: a comparative analysis in bats (Chiroptera)

K. Safi, D. K. N. Dechmann
2005 Proceedings of the Royal Society of London. Biological Sciences  
Acknowledgements: We are grateful to David Hosken for his invaluable support in statistical analyses and discussions that helped to improve this study. Rachel Page helped to initiate this work and  ...  The fact that the inferior colliculi of echolocating bats were correlated with wing area may reflect their improved ability to deal with increasingly difficult acoustic environments.  ...  Environmental influences may act differently on each of the several centres summarized under "auditory nuclei", and their functions may be only partly or not at all related to changes in the environment  ...
