Description

We are seeking 1 – 2 students to join us our Sound in Space research program, working within our McGill-based research team on our downtown Montreal campus and at the Centre for Interdisciplinary Research on Music Media and Technology (CIRMMT).

One of the major challenges to the auditory system is to track sound sources as they move to predict their future path and guide action (e.g. avoid an approaching car). Yet, dynamic sound localization - our ability to determine the position of sounds as they move in space - has largely been understudied due to the complications of laboratory setups. The long-term goal of this program is to understand the perceptual and cognitive underpinnings of auditory motion in an attempt to reconcile current theories of static and dynamic sound localization.

Our recent work (involving several ATIAM graduates) has demonstrated the existence of upper limits of auditory motion in a range of velocities that had not been explored before [1, 2, 3]. Based on this empirical work, we developed a model of auditory motion based on the comparison of static localization cues at successive points in time, constrained by the temporal resolution of the binaural system (blurred snapshot model) [4].

But our work so far focused on azimuthal localization using sounds revolving at a fixed distance on the horizontal plane. The student(s) will work on a series of laboratory experiments designed to validate our model and extend it investigate the contributions of different localization cues. We will train the student(s) on all aspects of the research process, from engaging the literature, designing controlled listening tests in laboratory settings, conducting statistical analyses, to writing publications and presenting. Students will assist with stimuli preparation, recruiting and running participants, analyzing data and reporting findings.

Students will work under the supervision of Prof. Catherine Guastavino. Comprehension of English is a major asset in working with our team, and students should feel comfortable in a bilingual work environment.
