Differences in Preference for Noise Reduction Strength between Individual Listeners
There is little research on user preference for different settings of noise reduction, especially for individual users. We therefore measured individual preference for pairs of audio streams differing in noise reduction strength. Data was analysed with a logistic probability model that is based on a quadratic preference utility function. This allowed for an estimate of the optimal setting for each individual subject. For five out of ten subjects the optimized setting differed significantly from the optimum obtained for the grouped data. However, the predicted preference for the individual optimum (60%) was only slightly higher than chance level (50%), which can be considered as too weak to advocate individualization of noise reduction for these normally hearing subjects. However, in hearing-impaired subjects this may be different.
