Cochlear Hearing Loss Clinical Trial
Official title:
Investigation of the Naída CI M90 Sound Processor in Various Acoustic Scenarios

Study type | Interventional |
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.

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 |
