Ph.D./M.Sc. Project:

Design of an electronic earpiece with embedded hearing assessment and restoration

General Information

Research  fields:     Design of an electronic earpiece with embedded hearing assessment and restoration

Advisors:    Prof. Jérémie Voix <Jeremie.Voix@etsmtl.ca>

Location:      École de technologie supérieure, Montréal, Quebec, Canada

Starting date:     Winter 2022 Semester


1        Description

The goal of this project is to design an electronic earpiece that can provide a robust way to monitor users’ hearing capabilities over time, as well as to automatically compensate for mild hearing loss through multi-band amplifica- tion, dynamic compression and equalization of audio playback. Currently, CRITIAS has experience in designing electroacoustic earpieces with calibrated microphone and receivers [1], and has further developed methods for precise measurement of in-ear levels [2-3]. The student will work on the development of audio equalization filters as well as multi-band dynamic compressors for increased speech intelligibility for users with mild hearing losses in low ambient noise conditions.

3        Location

École de technologie supérieure is located in Montréal, Québec, Canada. Often described as an appealing blend of North American and European culture, Montréal is a safe, multicultural city, nice to live in, with an affordable cost of living. Since its inception in 2016, Montréal has constantly ranked as Quacquerilli Symonds’ Best Student City in North America. Montréal is also recognized for its quality of life. Close to both peaceful rural beauty and exciting ski slopes, this dynamic city offers lively districts and many green spaces. Located in the heart of the city, the ÉTS campus is easily reached by bicycle or public transit.

Since its creation, ÉTS has pursued a mission that is deeply rooted in all its activities: To meet the needs of the industrial sector, which is in need of engineers who have not only a good theoretical background, but also practical knowledge. To fulfil this mission, ÉTS has a unique partnership with the business and industrial spheres that includes both small and large companies. It stands out from other universities in Quebec because of the applied training it offers students, as well as its research activities conducted by and for companies. Furthermore, this position is affiliated with the ETS-EERS Industrial Research Chair in In-Ear Technologies (CRITIAS) located at the Carrefour d’innovation INGO, which offers a unique and intimate relationship with the industrial partner EERS, located just across the hall.
