Gallaudet University is conducting a study to evaluate interference in cochlear implants from digital cellular telephones. Cochlear implant users may experience a "buzzing sound" when using a wireless phone which is caused by electromagnetic interference. Interference can have a range of adverse effects on the ability of the cochlear implant wearer to use a wireless phone. Due to interference, cochlear implant wearers may experience annoyance, reduced speech understanding or, in extreme cases, inability to use a wireless phone.

Participants must:

  1. be between the ages of 18-70 years of age
  2. be daily cochlear implant users
  3. have used cochlear implant(s) for at least 6 months
  4. use the telephone regularly for most calls(rather than text or video)

Compensation: $12 per hour

Location: Gallaudet University, Mary Thornberry Building

Duration: Up to 1 hour scheduled at your convenience

If you participate, you will be asked to:

  1. Complete an aided hearing test
  2. Complete a questionnaire
  3. Listen to speech and a variety of interfering noises
  4. Adjust and make ratings of speech and noise levels

This study has been approved by the Gallaudet University's Institutional Review Board. Participants' identities and results are kept confidential. The research is supported by the Rehabilitation Engineering Research Center on Hearing Enhancement (RERC-HE) and funded by the National Institute on Disability and Rehabilitation Research (NIDRR), an agency of the United States Department of Education (DOE). The RERC-HE is housed in the Department of Hearing, Speech and Language Sciences in the Mary Thornberry Building on the Gallaudet Campus. For more information on the RERC-HE we invite you to visit our website at www.hearingresearch.org.
