Research Projects

The Hearing Aid Research Laboratory conducts several research studies throughout the year. If you are interested in learning more about our research or if you would be interested in participating in a research study, please contact Kristi Oeding by phone at: 314-362-7496 or by e-mail at:

Current Research Studies:

The Division of Adult Audiology at Washington University in St. Louis School of Medicine is conducting a research study examining different methods of fitting hearing aids and how this could affect the user’s performance. Participants must be 18 years of age or older, have hearing loss that is equal between ears, no history of middle ear problems (surgery on the ears, hole in the eardrum, etc), and no previous hearing aid use. The study will last about 14 weeks and require five visits. At the end of the study, you will be compensated. You can either purchase the hearing aids at a significantly reduced cost or receive $100 for your time.

Past Research Studies:

  • Evaluation of a BICROS system with directional microphones on the receiver and transmitter sides (2014)
  • Differences in speech recognition in noise, sound quality judgments, and real-world preferences between two hearing aids differing in input dynamic range (2013)
  • The effectiveness of the directional microphone in the Ponto Pro (2011-2012)
  • Evaluation of the differences in sensation level between the Widex SoundTracker and the Frye and Verifit real-ear systems (2011-2012)
  • Impact of multi-channel noise reduction on speech recognition and comfort in noise for BICROS users (2011-2012)
