Clinical Trial Summary

In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of Naída Link M90 hearing aid and Naída CI M90 sound processor 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 that uses the investigational device is not large in general.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference in speech perception in noise with AutoSense OS on Naída M hearing devices and AutoSound OS on the clinically available Naída Q hearing devices	Difference in speech reception threshold of 50% speech understanding which is the signal to noise ratio in Decibel [dB] to understand 50% of the target speech between AutoSense OS on Naída M hearing devices and AutoSound OS on the clinically available Naída Q hearing devices.	6 weeks
Secondary	Differences in speech perception in noise threshold measured in Decibel [dB]	Differences are compared between AutoSense OS on Naída M hearing devices and the omnidirectional microphone setting on Naída Q hearing devices.; Min and Max values are -10dB and +10dB, whereas the smalller the value the better	6 weeks
Secondary	Differences in speech perception in quiet threshold measured in Decibel [dB]	Differences are compared between AutoSense OS on Naída M hearing devices and AutoSound OS on Naída Q hearing devices and the omnidirectional microphone setting on Naída Q hearing devices.; Min and Max values are -10dB and +10dB, whereas the smalller the value the better	6 weeks
Secondary	Differences in mono/stereo identification measured in % correct	Differences are compared between mono and stereo free-field presentation, mono and stereo streaming presentation, stereo free-field and stereo streaming presentation, mono free-field and mono streaming presentation, differences in music enjoyment ratings measured in rating score	6 weeks
Secondary	Differences in speech understanding in noise measured in % correct	Differences are compared between AutoZoomControl on Naída M hearing devices and the omnidirectional microphone setting on Naída Q hearing devices	6 weeks
Secondary	Differences in music enjoyment ratings measured in rating score	Differences are compared between; mono and stereo free-field presentation; mono and stereo streaming presentation; stereo free-field and stereo streaming presentation; mono free-field and mono streaming presentation	6 weeks
