Investigation of the Automatic Technology on the Naída M Hearing Devices

Completed

• Conditions: Cochlear Hearing Loss

• Registration Number: NCT04610216
• Lead Sponsor: Advanced Bionics AG

Brief Summary

In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of the device under investigation on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies.

Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population using the investigational device is not large in general.

Detailed Description

The primary endpoint of this clinical investigation is the difference in speech intelligibility measured in percent correct with AutoZoomControl compared to an omnidirectional microphone on Naída M hearing devices.The Naída CI M90 sound processor is a behind-the-ear (BTE) sound processor based on the Phonak Marvel hearing aid platform. It replaces the market approved Naída CI Q-Series processors. The Naída Link M90 hearing aid is a behind-the-ear (BTE) hearing aid based on the Phonak Marvel hearing aid platform. It is especially designed to be used for bimodal CI users equipped with a Naída CI M90 sound processor.

Primary Outcome Measures

Name	Time	Method
Difference in speech intelligibility in noise	2 months	The primary endpoint of this clinical investigation is the difference in speech intelligibility measured in percent correct with AutoZoomControl compared to an omnidirectional microphone on Naída M hearing devices. The French Matrix Test will be used and percentage correct will be recorded.

Secondary Outcome Measures

Name	Time	Method
Differences in localization abilities	2 months	AutoZoom control versus Omnidirectional microphone, ZoomControl versus Omnidirectional microphone and AutoZoomControl versus ZoomControlon Naída M hearing devices will be compared.; The directions (0,+/-90,180 degrees) from where the sentences of the French Matrix Test are presented have to be determined.; Percentage correct will be recorded.
