Speech Perception for Children With Cochlear Implants

The purpose of this study is to determine whether speech recognition in noise can be improved
by the addition of a special listening program to the sound processor. Thus we propose to
assess speech perception in noise for pediatric cochlear implant patients using both their
everyday listening program as well an ASC program.

You will be asked to listen to sentences in quiet and in noise and repeat the sentences. You
will be seated in a comfortable chair inside the sound booth with 8 loudspeakers placed in a
circular pattern around your head. We will test your sentence recognition abilities in your
listening program as well as in the new listening program. The sentences and noise will be
presented through loudspeakers at levels typically encountered in everyday communication
environments. Your participation would involve approximately 20 minutes of testing plus 10
minutes to add the new listening program to their processor.

Inclusion Criteria: Children with bilateral sensorineural hearing loss who have 1) one or
two Nucleus 24 series cochlear implants, 2) at least 1 year experience with their cochlear
implant, and, 3) the ability to score > 50% correct for HINT sentences in quiet.

Exclusion Criteria: 1) Patients under 4 years of age or over 17 years of age, 2) patients
who have had at least 1 year experience with their cochlear implant and, 3) patients who
score > 50% for HINT sentence recognition in quiet
