Comparison of the New Fitting Method Cochlear Nucleus Fitting Software (NFS) With the Established Fitting Method Cochlear Nucleus Custom SoundTM Suite (CSS)

January 9, 2018 updated by: Cochlear

Comparison of Fitting Methods Using Cochlear Clinical Care Innovation

The purpose of this study is to evaluate if the new and simplified fitting method with Cochlear Nucleus Fitting Software (a major component of a suite of tools which form the Clinical Care Innovation) provides Cochlear Implants Recipients with the same hearing outcome as the current and established clinical fitting method with Cochlear Nucleus Custom SoundTM Suite. The Clinical Care Innovation method reduces fitting to simple volume, bass and trebles adjustments, operations which are familiar to anyone who has used an audio player.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
