Intervention Model

SINGLE_GROUP

Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

There is no masking in this study as all participants receive all MAPs (single group study model). The term "single-blinded" in the official title refers to the fact that participants are blinded to the order in which they receive the MAPs.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MAPs on Cochlear™ Nucleus® 7, Nucleus® 8 and Kanso® 2 Sound Processors

Participants will receive four different MAPs to use during two take-home periods and will then complete hearing assessments using each MAP.
