  • Evaluating degree of amenity in train cabin noise using Optical Topography

説明

<p>From past research, when the riding comfort of the E5 Series High-speed train was evaluated by optical topography, the stress felt while riding was affected by various external influences other than vehicle vibration, and reflected the overall comfort of the vehicle. Therefore, in this study, we focused on the cabin noise in the High-speed train, which is considered to be one of the major factors that determine the comfort inside the High-speed train, and objectively evaluated the comfort against the cabin noise in the High-speed train by optical topography. As a result, there is a correlation between the discomfort index of High-speed train in-vehicle noise and the stress brain index, and the effect of cabin noise on the in-vehicle comfort of the High-speed train can be accurately evaluated by optical topography, and the predictable discomfort formula considering the sound quality index is used. It was clarified that the evaluation method can be used to evaluate the comfort of cabin noise in the High-speed train.</p>
