Comparison Between Neuro 1 and Neuro 2 Cochlear Implant Speech Processors

2017-09-21 02:23:22 | BioPortfolio


The present study aims to evaluate patient satisfaction and audiological performance with their current cochlear implant speech processor, the Neuro 1, and to compare it with the satisfaction and performance obtained with the new speech processor, the Neuro 2.


Nowadays, cochlear implants (CI) are successfully used to rehabilitate severe to profound sensorineural hearing loss. Oticon Medical recently developed a new cochlear implant system, including a new implantable internal part (Neuro Zti) and a new speech processor (Neuro 1). This new speech processor automatically detects and adapts to the sound environment, increasing the ease of listening in all situations. A second version of this speech processor has very recently been developed, called the Neuro 2. The Neuro 1 and 2 share the same signal processing characteristics and the "sound" delivered to the patient is similar. However, the Neuro 2 offers better ergonomics (smaller size and weight, rechargeable batteries…). Some improvements available on the Neuro 2 may be particularly interesting for children.

The aim of the present study is twofold: 1. Compare the satisfaction of adult and pediatric users for the speech processor Neuro 1 with their satisfaction for the Neuro 2, and 2. Show that audiological outcomes are at least as good for the Neuro 2 than for the Neuro 1.

The participants come at the hospital for three visits. The Neuro 1 is evaluated during the first visit (V1). Evaluation of the Neuro 2 takes place during the second (V2, 15 days after V1) and the third (V3, 3 months after V2).
