The study is about the importance of each follow-up visit after activating a new cochlear implant in addition to evaluating the effectiveness and efficiency of a new programming strategy from Cochlear Americas. Investigators are looking for patients who have recently selected Cochlear Americas as their cochlear implant manufacturer of choice for their upcoming surgery. The aim of this study is to determine if 1) patient outcomes remain stable when reducing follow-up appointments and 2) Cochlear's population mean mapping can produce similar outcomes with patients while additionally reducing appointment times. The hypothesis is that using population mean mapping and reducing the number of follow-up visits after activation will yield similar performance outcomes to a standard of care while decreasing the length of appointment times and number of appointments needed for each patient.

Traditional follow-up includes the following visits after activation: 1-week, 1-month, 3-months, 6-months and 1 year. With the intervention used, the 1-week follow-up is removed.
Traditional mapping at activation involves the measurement of at least 5 electrodes (both T-levels and C-levels). The intervention uses a population mean mapping strategy where there is a pre-set dynamic range of 46 CL with a spot check of C-levels.

RECRUITINGSpeech perception scores
Speech perception scores via CNC word lists (percentages) at each visit. Scores are from 0 to 100% with 100% being the best.
Time frame: 1-year
Duration of programming session
Time spent programming (seconds) at each visit
Time frame: 1-year
Quality of Life questionnaire
Patient outcomes via the Cochlear Implant Quality of Life-35 Profile questionnaire at each visit. Scores are out of 35 points and higher scores indicate better quality of life.
Time frame: 1-year
Soundfield detection thresholds
Change in soundfield detection thresholds (dB HL) between each visit. Detection thresholds should be between 20 and 35 dB HL and anywhere in that range is good.
Time frame: 1-year
programming levels
Change in programming levels between each visit (converted measure from CL to charge units). There is no indication of good and bad with programming levels, we are just measuring what they are and how stable they are over time.
Time frame: 1-year
