Sound pitch settings for a new cochlear implant in single-sided deafness

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with deafness in one ear who will get a cochlear implant, or have one not yet switched on. The other ear must hear normally or nearly normally.

Age

18 years or older

Sex

All sexes can join

Disease stage

Deafness in one ear (single-sided deafness) with normal or minimal hearing loss in the other ear

Earlier treatment

Plans to receive a cochlear implant in one ear, or has one that has not yet been switched on

Main reasons for not taking part

• Under age 18
• A known abnormal shape or structure of the implanted ear
• Does not speak English
• More than minimal hearing loss in the other ear

The registry criteria, word for word

What the trial wants to find out

The goal of this study is to study the adaptation process in newly implanted Single-Sided Deaf Cochlear Implant (SSD-CI) users. Subjects will use four frequency maps for the first month after CI activation. One of these maps will be standard of care and the other three will have higher low frequency edges than the standard of care default maps. These maps will alternate daily during the first month (with exceptions made for situations when the subject is allowed to use a preferred map rather than the map predetermined for use that day), and after that point each subject will make a selection at the beginning of the week to compare all four maps and decide which one to use at the beginning of the following week. The goal of this study is to investigate how reducing place-pitch mismatch in SSD CI users affects 1) sound quality, 2) device use, and 3) speech perception.

The group in the trial

• Newly implanted Single-Sided Deaf Cochlear Implant (SSD-CI) UsersTreatment being tested

  Subjects will use four frequency maps for the first month after CI activation. One of these maps will be standard of care (i.e., 188-7938 Hz for Cochlear users) and the other three will have higher low frequency edges than the standard of care default maps (starting at 313, 438, and 563 Hz, respectively). These maps will alternate daily during the first month (with exceptions made for situations when the subject is allowed to use a preferred map rather than the map predetermined for use that day), and after that point each subject will make a selection at the beginning of the week to compare all four maps and decide which one to use at the beginning of the following week.
