Participants

We are always looking for participants for our projects on speech perception, aging, and hearing loss.  For many projects, we seek young adults with normal hearing; for other projects we seek older adults with either normal hearing or hearing loss.  We also have projects that examine speech understanding performance of hearing-impaired adults who wear hearing aids. To see if you qualify for a specific study, please see the below opportunities.


Auditory temporal processes, speech perception and aging

This project examines younger and older listeners' ability to understand speech that features altered timing.  The current projects specifically examine perception of Spanish-accented English.  We are currently looking for adults with the following characteristics: 

  • Age: 18-40 years and 65-80 years
  • Participant Hearing: normal hearing or hearing loss (mild-to-moderate hearing loss)
  • Must be a native speaker of Spanish
  • Time Commitment: 10-12 hours, scheduled in sessions of 2 hours/each
  • Reimbursement:  $12/hour

Multi-Site Study of the Efficacy of Speech Perception Training for Hearing Aid Users

This training study evaluates the benefits of a computerized training program for improving speech recognition by hearing aid users.  We are currently enrolling participants and seek adults with the following characteristics: 

  • Age: 21 years and older
  • Participant Hearing: Hearing Impaired
  • Must be a hearing aid user who has worn hearing aids for at least 3 months
  • Time Commitment: 30 hours, scheduled in 2-hour visits
  • Reimbursement:  $500 for participation in the entire study

Functional Hearing Evaluation for Military Occupational Specialties

This project assesses the functional performance of normal-hearing and hearing-impaired individuals in real-world settings. Participants will be tested in groups of 3 to 4 in a noisy setting on campus. We are currently seeking adult participants with the following characteristics:

  • Age: 18-80 years
  • Participant Hearing: Normal hearing or hearing impaired
  • Time Commitment: 2.5 hours, one-time session or 3 hours, two sessions
  • Reimbursement: $10/hour

Effect of Frequency Manipulations on Spatial Release from Masking in Simulations of Cochlear Implants for Single-sided Deafness in Competing Talker Situations

The purpose of this study is to evaluate the effects a frequency mismatch will have on speech understanding in simulations of cochlear implants for single sided deafness. The task involves listening to a target talker and ignoring masker talkers, some of which are vocoded to simulate what a CI user might hear. We are currently seeking adult participants with the following characteristics:

  • Age: 18-50 years
  • Participant hearing: Normal Hearing
  • Time Commitment: 2 hours scheduled in one or two sessions
  • Reimbursement: $10/hour
