Summary
A new behind-the-ear cochlear prosthesis speech processor was developed. While performance was comparable, speech perception from open lists was better with the conventional device, indicating potential for size reduction without significant performance loss.
Area of Science:
- Audiology and Speech-Language Pathology
- Biomedical Engineering
- Medical Devices
Background:
- The Vienna cochlear prosthesis is a hearing device requiring a speech processor.
- Conventional speech processors can be bulky, impacting user comfort and aesthetics.
- Advancements in speech processing strategies may allow for miniaturization.
Purpose of the Study:
- To design and evaluate a novel, smaller behind-the-ear wearable speech processor for the Vienna cochlear prosthesis.
- To compare the performance of the new processor against the conventional device.
Main Methods:
- A new behind-the-ear speech processor was designed for the Vienna cochlear prosthesis.
- A comparative study involving 6 patients was conducted.
- Patients used the new device for one week before undergoing auditory testing and speech tracking.
Main Results:
- Auditory test battery results and speech tracking performance were similar between the new and conventional processors.
- Speech perception from an open-list test was superior with the conventional processor.
- The study suggests substantial size reduction is possible by modifying speech-processing strategies without major performance degradation.
Conclusions:
- Miniaturization of cochlear prosthesis speech processors is feasible through modified speech-processing strategies.
- Further studies with more patients and longer usage periods are needed to validate the new device's long-term efficacy and user experience.
