Research
We conduct a broad range of terrestrial, aquatic, and marine bioacoustic research, often at large geographic scales. Many of our projects are applied, featuring a strong focus on the conservation of endangered species. More recently we have engaged in soundscape ecology research and the development of acoustic metrics to assess biodiversity and ecosystem health. We are also researching new ways to collect and analyze acoustic data sets using autonomous mobile systems and algorithm development. Here is an overview of our current research portfolio:
- Soundscapes, Acoustic Habitats, and Biodiversity
Soundscapes and acoustic habitats are complex and comprised of a variety of biological, geophysical, and anthropogenic acoustic signals. Much of our research in this area focuses on the assessment of spatiotemporal variability in ambient noise levels and how the various acoustic…
- Passive Acoustic Monitoring
Passive acoustic monitoring (PAM) of terrestrial and marine animals and ecosystem at ecologically appropriate scales has always been an integral part of the Yang Center’s work. We have extensive experience in the design and execution of PAM projects. Typically, these…
- Mobile Autonomous Vehicles
Mobile autonomous vehicles equipped with acoustic sensors allow us to collect data on animal abundance and assess distribution with high spatial and temporal resolution in remote and inaccessible areas. The Yang Center has been involved in the development of acoustic…
- Elephant Listening Project
Bioacoustics researcher Katy Payne is co-founder of the Elephant Listening Project, which uses acoustic methods to study and aid in the conservation of forest elephants in Central Africa.
Our Story
Elephants use low frequency sounds to communicate. These sounds are mostly below…
- Algorithm Research and Modeling
Over the past two decades, the Yang Center has collected large amounts — literally, hundreds of years — of acoustic data. To keep up with the analysis of the data, we develop detection, classification, and localization (DCL) algorithms to efficiently…
- Acoustic Communication and Behavior
The study of animal acoustic communication and behavior is currently one of our smaller but steadily growing research areas. Understanding the acoustic behavior of animals, which often varies with time of day, season, and by sex and age class, is very…
