The Impact Of The Sound Resources Of Waiting Halls Of High-speed Railway Elevated Stations To The Emotion

This article takes the waiting hall of the west of the Harbin railway station for the study subject, studies the impact of sound resources and the characteristics of sound source of the waiting hall of the oversize high-speed elevated railway station to the mood. First of all, it studies the sound resources in the daily and simulation of the fire situations respectively,to obtain the impact of the different sound resources to the mood. On this basis, further summarizes the main factors that affects the sound source emotional evaluation(for everyday situations of sound source type). And then analyzed how the experimental environment, SPL and reverberation time(the spatial size) and so on affect the emotional evaluation of the sound resource, so it can raise method on how to improve the emotional experience.The results show that in the first place, the emotional experience of fire cases is bad than the daily cases. In both cases,the emotional experience of vocals is the worst. the emotional experience of the music and broadcast is the best, the fire siren can relieve the anxiety of the people who trapped in the fire,but the brawl between each other is contributed to the unease.Secondly, using the factor analysis of SPSS to analyze the emotional evaluation of the daily sound resources, and the results show that the main factors to affect mood valid dimension is the characteristics of the sound source itself.While the main factor affecting the arousal dimension is the relative relationship between the tester and the sound and the memories about the sound.Finally, the difference of the experimental environment, the SPL, the reverberation time(the spatial size), and other factors can influence the mood in different level. Reduce the sound pressure level can improve the emotional experience of all sound resources except the music. To increase the Space scale can enhance the emotional experience. The impact of the experimental environment factor is not obvious.And the background sound and the sudden sound can make difference.Finally, the gender and the number or the tempo of the footsteps also can affect the emotional evaluation.
