Associate Professor Magnus Wahlberg's main focus is on bioacoustics of aquatic animals (fish, marine mammals and marine birds). His current work is focusing on hearing in marine mammals and birds as well as the predator-prey interactions of fish and of fish and marine mammals. Besides bioacoustics, Magnus is also involved in research and teaching of scientific outreach.
In our lab we focus on the study of the sensory physiology of hearing in aquatic animals, such as marine mammals, fish and marine birds. We use psychophysical techniques (which include training of the animals) and ABR methods. We also study echolocation of toothed whales, with special interest on the harbour porpoise biosonar, focusing on how they use and produce sound to avoid obstacles, track and select prey, escape predators and communicate. For that we mainly use hydrophone (underwater microphone) arrays to assess the position of the emitting animal and focus on studying the intensity and directionality of their biosonar during different tasks.
The studies are based in the Marine Biological Research center (Kerteminde, University of Southern Denmark) where we keep cormorants and grey seals for the hearing research. We also collaborate with the adjacent Fjord&Baelt center doing research on harbour porpoise and harbour seals mainly on their echolocation and behaviour. Field work is made all over the world to study the acoustic behavior of marine mammals and fish, and how they are affected by human factors sutch as fishing and artificial noise.
