Outcomes
Primary Outcomes
Acceptability Ratings for the CP950 Sound Processor Compared to Subjects' Own Processors, Summarized by the Overall Hearing Performance Score.
Time Frame: 14 days
Each subject used the Investigational device (CP950) for take home use to obtain subjective ratings. During the take home use, A subjective questionnaire was asked them to recall and rate how their hearing performance with the Investigational device CP950 OTE processor compared to their hearing performance with their own CP810, CP910 or CP920 BTE processor. Likert scale was used for each rating in the questionnaire for at home usage ( with the values ranging from) : 1 = much worse; 2 = somewhat worse; 3 = No difference; 4 = somewhat better; 5 = much better.
Secondary Outcomes
- Percentage of Correct Words Scored With Sentences in Noise With the CP950 Sound Processor(In booth testing 1 day)
- Speech Reception Threshold (SNR50) for Sentence Testing in Noise With CP950 Sound Processor .(in booth testing 1 day.)
