This study evaluates the benefit of Neuro 1 sound processor upgrade in speech perfomance in adults. Half of participants will be tested with Neuro 1 first and Neuro 2, while the other half will be tested with Neuro 2 first and then Neuro 1.
The Neuro 1 processor represented a technological advancement over past models, particularly in detecting the environment and automatically adjusting to the sound environment. A second version of the Neuro 1 processor has been developed, the Neuro 2. The signal processing and stimulation characteristics are similar, so speech comprehension levels are expected to be equivalent. This study is designed to compare Neuro 1 and Neuro 2 in terms of audiometric performance.
