The XXIXth International Bioacoustics Congress will be held at Lundsgaard Manor in Kerteminde, Denmark, from 7 to 12 September 2025.
The International Bioacoustics Society (IBAC) was founded in Århus, Denmark, in September 1969. Its aim is to promote international participation in the whole field of bioacoustics. Its main achievement since then has been the organisation of twenty-seven bioacoustic symposia and congresses in thirteen different countries.
Biology and physical acoustics
Bioacoustics is the scientific study of biological sounds. It covers the following subjects :
- Sound production in animals, including anatomy and neurophysiological processes
- Sound propagation in water and air
- Vibratory communication in insects
- Biosonar or echolocation in bats and dolphins
- Ultrasonic signals (>20,000 Hz) in insects, rodents, bats and dolphins
- Infrasonic signals (<20 Hz) in large mammals
- Sound reception capabilities and mechanisms of animal hearing
- Ethology of animal acoustic communication
- Evolution, ontogeny and development of acoustic behaviour
- Relationships between animal sounds and their environment
- Effects of human-produced sounds on animals
- Computer analysis of acoustic signals and machine learning for taxonomic studies and biodiversity benchmarking
- Practical bioacoustic applications in wildlife monitoring and pest control
The development of bioacoustics dates back to the 1950s, when practical recording and analysis methods became readily available to the scientific community. The subject of bioacoustics is essentially a marriage between the fields of biology and physical acoustics. Given its multidisciplinary nature, IBAC aims to bring together, in an informal setting, biologists of different specialities (ethologists, physiologists, taxonomists, etc.) with engineers, sound archivists and amateur sound recordists, in order to encourage discussion and the exchange of ideas.
The International Bioacoustics Society is a non-profit organisation registered in Saint-Étienne, France, in 2019.
Location : Kerteminde, Denmark
Dates : 7-12 September 2025.
