Evaluation of a Wind Noise Reduction Method Using DNN for Bicycle Audio Augmented Reality Systems

摘要

In a previous study, we studied wind noise reduction methods to use with navigation systems for bicycles. As a result, the Wiener (iteration) filter was superior in wind noise elimination performance, and it was able to give a very high navigation speech intelligibility. However, not only the wind noise but also the environmental sounds were overly attenuated. Therefore, in this paper, DNN was introduced to wind noise reduction, Wind noise reduction and environmental sound performance were evaluated. As a result, it was concluded that DNN has high wind noise removal performance while environmental sound can be preserved.
