Investigation of the Automatic Technology on the Naída M Hearing Devices

Advanced Bionics AG12 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Difference in speech intelligibility in noise

Time frame: 2 months

Secondary Outcomes

Differences in speech perception in noise

ZoomControl versus Omnidirectional microphone and AutoZoomControl versus ZoomControlon Naída M hearing devices will be compared. The French Matrix Test will be used and percentage correct will be recorded.

Time frame: 2 months

Differences in localization abilities

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.

Time frame: 2 months
