Applications are sought for a PhD position at Sorbonne University (Paris).​
​The successful candidate will be jointly supervised by Dr. Lapo Boschi at
the Earth Sciences institute (ISTEP), Dr. Anthony Herrel at the National
Museum of Natural History (MNHN), and Dr. J. Marchal at the d'Alembert
institute (IJLRA).

Most literature concerned with the evolution of sound localization
postulates that this task is accomplished by means of three, well
established auditory cues, at least in mammals. The first is binaural or
interaural time-difference (ITD): the auditory system compares the arrival
time of a sound at the two ears to determine its azimuth. The second is the
binaural or interaural intensity or level difference (IID or ILD): the
difference in the intensity of a sound is used to determine azimuth.
Finally, mammals evolved external ears, or pinnae,
that alter the spectrum of a sound as a function of source location;
monaural pinna cues enable an animal to avoid front-back confusions and
localize sound in the vertical plane. It has been suggested that this
simple model is insufficient to explain the resolution, target detection,
localization and tracking abilities of the biosonar system in odontocete
cetaceans (dolphins and toothed
​ ​
whales). The research that we propose to conduct questions the
ITD/ILD/spectrum idea, suggesting that the brain of odontocete cetaceans
might be capable of analyzing acoustic waveforms in more sophisticated and
​ ​
effective ways. Our work will contribute to constraining the nature of the
sound localization algorithm encoded in the odontecete brain, bridging the
gap between physicists who think of sound localization and other auditory
tasks in terms of data processing, and psychoacousticians and biologists
whose experimental work provides data on the auditory performance in living
organisms. It will contribute to a better understanding of the mammalian
brain, and inspire the
evelopment of new sound localization systems, useful to a variety of
applications e.g. in robotics, seismology, and physical acoustics.
