Jan de Laat, PhD, studied physics at the Eindhoven University of Technology and prepared his thesis, "The perception of fluctuating sounds by hearing-impaired listeners," at the Free University Medical Center in Amsterdam. He is a medical-physicist and audiologist connected to the Department of Audiology at Leiden University Medical Center. His scientific expertise lies in developing and applying new diagnostic tools for hearing-impaired children and elderly, spanning both electrophysiology and psychophysics.
Jan is also a member of the advisory board of several foundations, including the Netherlands Ear Foundation and the Dutch Association for the Hard of Hearing, and serves on the board of reference of the Health Council of the Netherlands.
Clinical Advisory Board Member
Jan is part of the Freequency Clinical Advisory Board. His research background in diagnostic tools and hearing assessment helps ground Freequency's approach in established audiological science.
Co-author of the Freequency white paper
Jan co-authored a white paper alongside Cathelijne van der Zwan, analyzing user-reported outcomes from 110 Dutch Freequency users. The study tracked Tinnitus Functional Index (TFI) scores over time and found that 41.8% of users achieved a clinically relevant improvement, with 32.7% reaching a clinically significant improvement. The mean TFI score dropped from 48.1 to 41.0.
This research forms part of the evidence base behind Freequency's approach.
