CENTRALE LYON - PhD position: Adaptive Sound Field Synthesis

This PhD project aims at developping and testing an adaptive Sound Field Synthesis (SFS) system for human listeners, to be used for hearing aid research.

A first task will consists of a bibliographical survey of SFS techniques using a loudspeaker array for hearing aid research1234. Based on these knowledge, the candidate will developp an adaptive SFS algorithm based on state-of-the art transaural approaches4 using a loudspeaker array and a dummy head. This algorithm will be implemented and tested in real-time in the lab, in collaboration with the Postdoc researcher #1 and the help of a Master 2 intern. In a second time, adaptive SFS techniques using modal approachs (i.e. Ambisonics) will be investigated. After validation, this system will be used for speech intelligibility tests in virtual reverberant room.

We offer¶

• As part of the ASFHEAR project, we offer an stimulating working environment within a research team in the Lyon area (see the team).
• The are opportunities of teaching at École Centrale de Lyon and/or in the international MSc in Acoustics.
• The candidate will conduct his PhD inside the doctoral school MEGA. The latter help doctoral students develop a career plan throughout their thesis, by offering a wide range of training courses, and promoting interdisciplinary work, relations with companies and international contacts.
• Lyon city and surroundings offer rich opportunities for culture and outdoor activities.

Qualification requirements¶

Master degree in acoustics and/or signal processing,

Fluent oral and written communication skills in English,
