About

The goal of this clinical trial is to determine if a new algorithm can improve speech perception for cochlear implant users. The main questions it aims to answer [is/are]:

• Does the algorithm improve speech perception in noisy environments?
• Does the algorithm allow listeners to determine where a sound is coming from?

Participants will

• Listen to and repeat sentences presented in the presence of noise
• Indicate the location that sounds originated from

Enrollment: 25 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Participants must have bilateral cochlear implants from Cochlear or Advanced Bionics

Exclusion criteria

• Non-native English speakers
