Hearing protection - biomonitoring and behavioral effects

Competences: 
  • Biomonitoring of short-term effects of noise exposure on hearing and well-being in real-life conditions including continuous monitoring of otoacoustic emissions (OAE's) at the work floor.
  • Assessing speech perception, sound localization and sound perception for passive and active hearing protectors.
  • Evaluating beliefs, opinions and use of hearing protection at the work floor.
  • Evaluating the attenuation of custom-made hearing protectors using microphone-in-real-ear measurements (MIRE) accounting for individual transfer functions.
  • Development of auditory EEG protocols for integration with wearables and monitoring systems

Research projects: 
  • FWO postdoctoral fellowship: Functional high resolution monitoring for instantaneous effects of noise on hearing and functioning.
  • PhD project: A body sensor system for continuous hearing health monitoring to study and reduce the risk of occupational hearing loss.
Collaborations: 
  • École de Technologie Supérieure (ÉTS, Montréal)
Tools and Valorisation: 
  • (Prototype of) in-situ OAE measurement device.
  • Measurement protocol for speech perception and sound localization.
  • Validated questionnaire on beliefs, attitudes and use of hearing protection.
  • Numerical model (FDTD) of the occluded ear canal.
