Updated on 2 April 2021


In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of Nada Link M90 hearing aid and Nada 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.
