Sound quality is becoming more critical in the automobile industry, and it is expected that acoustic innovation will be possible in the railway sector. Sound quality can be effectively enhanced at the design stage. The sound pressure level is calculated using the SEA technique, by predicting the interior noise of a train based on vehicle manufacturing information and design. There is a limit to predicting the perception of the passenger. In the development of future rail vehicles, noise that is different from the existing railway noise will occur. In this paper, the noise generated in the cabin during actual railroad driving is recorded using an ambisonic microphone. The sound field reproduced in the test room is compared with the target sound field and the appearance of the sound pressure level, frequency characteristics, and sound quality analysis at a similar level is determined. Through this study, primary performance verification is performed to build a spatial sound field reproduction system for train cabin noise. Further, studies on subjective sound perception and the sound design of train cabin noise will be conducted to utilize it as a virtual test platform.
