Evidence suggests that cognitive capacity predicts the ability to benefit from specific compression release settings in non-linear digital hearing instruments. Previous studies have investigated the predictive value of various cognitive tests in relation to aided speech recognition in noise using compression release settings that have been experienced for a certain period. However, the predictive value of cognitive tests with new settings, to which the user has not had the opportunity to become accustomed, has not been studied. In the present study, we compare the predictive values of two cognitive tests, reading span and letter monitoring, in relation to aided speech recognition in noise for 32 habitual hearing instrument users using new compression release settings. We found that reading span was a strong predictor of speech recognition in noise with new compression release settings. This result generalizes previous findings for experienced test settings to new test settings, for both speech recognition in noise tests used in the present study, Hagerman sentences and HINT. Letter monitoring, on the other hand, was not found to be a strong predictor of speech recognition in noise with new compression release settings.
