We propose a speech navigation system using augmented acoustic reality for bicycle. For that, an audio presentation device such as an earphone is necessary, but blocking the ears blocks the environmental sound. This leads to the risk of not being able to notice approaching cars and the like. Therefore, a microphone and a earphone are integrated in to a hear-through earphone which transparently presents ambient environmental sound. In using this, there is a problem that not only environmental sound but also wind noise is acquired, so it is difficult to hear navigation sounds and environmental sounds. On the other hand, wind noise reduction methods have been proposed in previous research. In this research, various noise reduction methods under conditions actually used in real time on the bicycle are systematically evaluated and compared, and the optimum wind noise countermeasure is examined. Therefore, the effect of wind noise reduction by the wind noise reduction method was evaluated in terms of the intelligibility of the augmented navigation voice. In addition, we evaluated the influence on the environmental sound by the wind noise reduction method based on the environmental sound direction perception accuracy. As a result, Wiener itaration filter was found to be the most effective for wind noise reduction, but the use of high pass filter and windshield is also a well-balanced method. |
