For Patients and Visitors
Vanderbilt University Medical Center: For Employees, Researchers, and Students


Thank you for visiting the Cochlear Implant Research Laboratory at Vanderbilt



The Cochlear Implant Research Laboratory at Vanderbilt focuses on speech perception, speech and language function, and basic auditory function as associated with the combination of electric and acoustic hearing—particularly with respect to preservation of acoustic hearing in the implanted ear.  Additional interests currently under investigation in the lab include binaural hearing with bilateral cochlear implants and/or hearing preservation, image-guided programming for cochlear implants, and pre-implant prediction of postoperative outcomes.



There are many opportunities for research participation in any of our ongoing studies. For additional  additional information about any of the ongoing projects, please click on the links below.

REDCap Survey of CI Audiologists in the United States


CI Audiologist Survey: April 2014

On April 28, 2014, the CI Lab Director, Dr. René H. Gifford and Dr. Michael Dorman--of Arizona State University--sent out an online survey invitation to 185 audiologists' email addresses associated with CI clinics in the United States as listed on the 3 FDA approved CI manufacturer's websites.  Of the 185 survey email invitations, 32 were immediately returned as undeliverable due to incorrect or defunct email addresses; thus the survey was successfully delivered to 153 CI audiologists.  We received 45 responses to the survey for an overall response rate of 29.2%.

The survey questions referenced the following hypothetical graph.  For access to the full survey text and the graphical results, please here click here.
