While wearable technologies are everywhere, they have not (yet) been configured for the ear. According to the World Health Organization, more than 1.1 billion people daily put their hearing at risk either at work or leisure. The NSERC-EERS Industrial Research Chair in In-Ear Technologies (CRITIAS) will address this challenge by developing leading-edge technology combining in-ear instrumented hardware platforms with audio signal processing and biosignal extraction algorithms. This technology will enable its Canadian industrial partner, EERS Technologies 4.0 Inc., to commercialize in-ear wearables for hearing protection, hearing aid, two-way communication and brain-computer interfaces for industrial, military, consumer and medical markets.

The first objective of the Chair will be to develop a versatile in-ear hardware platform with the team at EERS, using a proprietary technology that instantly custom molds the device (SonoFit). The platform, dubbed the Auditory Research Platform (ARP), will be equipped with several discrete sensors, electroacoustics transducers, electronic circuitry and a digital signal processor. The processor will run audio signal and biosignal processing algorithms, which will be developed as part of the research program.

The core research activities will include three areas of expertise:

  • digital hearing protection
  • communication in noise
  • in-ear sensing

The proposed research chair will further strengthen and sustain this successful industrial-academic collaboration, train about two dozen students and researchers, and create an innovative ecosystem to retain this unique expertise in Canada.
