Research Opportunity for Adult Cochlear Nucleus Implant Users

Research Opportunity for Adult Cochlear Implant Users 
Seeking Individuals in Maryland, Virginia and D.C.

The Dept. of Hearing, Speech, and Language Sciences at Gallaudet University is seeking adult CI users who are fluent in spoken English and who use a Cochlear Corporation (Nucleus) device to participate in a study of speech understanding and listener experience with MAP adjustments (i.e. frequency distribution changes based on user input).

Your participation may involve a couple visits over a 4-6 week time span. You will complete speech understanding tasks and compare sound quality, intelligibility, and preference for various MAP adjustments. MAP adjustments will be made on a device that we provide you (and never on your own personal device). You may also be asked to complete a trial period with your chosen frequency adjusted MAP. Finally, you will complete questionnaires about your experience.

Participants will be compensated $12/hour. This study has been approved by Gallaudet’s IRB. If you are interested in participating please contact: join@hearingresearch.org

How It Works: A Laser-Powered Ear Implant to Boost Hearing

May 29, 2012 in Technology

By Rebecca Boyle, Popsci 4/11/2012

Hearing loss from weapons and explosive devices has been the No. 1 disability in this country’s modern military conflicts, saddling thousands of veterans with anything from tinnitus to deafness. Now a new generation of laser-based implants promises to restore their hearing — and that of civilians, too — with higher resolution than existing technology.
Rather than stimulating inner ear auditory cells with electricity, or modifying them to respond to light directly, new laser-based cochlear implants will stimulate cells with heat. Here’s how it works.
Cochlear implants are widely available, albeit very expensive, but they can only restore very little of a person’s hearing. Current models can produce four to eight frequencies of sound, by stimulating nerves in the cochlea — the snail-shaped part of the inner ear — with eight separate electrodes. Click here to hear what it sounds like. Eight is not enough, explains Mark Bendett of Lockheed Martin Aculight, which is developing the laser-based technology.   Read more . . . →
