Ole Larsen lab

SOUND COMMUNICATION AND BEHAVIOUR GROUP

Associate Professor Ole Næsbye Larsen PhD, studies different aspects of acoustic communication in a variety of experimental animals both in laboratory and field.

In collaboration with Professor Torben Dabelsteen, KU, he studies acoustic communication in parrots (Orange-fronted Conures) both in their natural habitat in Costa Rica and in a psychoacoustic setup in the lab. The project focuses on information exchange in fission-fusion flocks. Additionally, he and Torben study sound propagation in the field and possible sound signal adaptations in both Conures in Costa Rica and Swift Foxes in Colorado, USA.

 

In collaboration with Magnus Wahlberg and Jakob Christensens-Dalsgaard he studies underwater hearing in diving birds (Cormorants and others) using psychoacoustic methods combined with measurements of auditory brainstem responses and eardrum vibrations using laser vibrometry.

 

In another project together with Jakob Christensens-Dalsgaard he studies anatomical and physiological adaptations to directional hearing mainly in birds (Zebra Finches, Barn Owls, Ostriches, Tinamous and others) to elucidate function and evolutionary perspectives.

 

Lately he has returned to studying directional hearing in the complicated 4-input system of the cricket ear in collaboration with Martin Lankheet and Johan L. van Leeuwen, University of Wageningen, NL.

 

In the past Ole was involved in pioneering studied of sound production in the avian syrinx. These studies are now continued by Coen Elemans with whom he collaborates. Ole is also interested in unconventional mechanisms of sound production, e.g. in animals using non-laryngeal accessory structures such as teeth and air sacs (e.g. the walrus in collaboration with Colleen Reichmuth, UCSC, USA).
