【摘要】：以我國新建的8個特大型高鐵車站的高架候車廳為研究對象,采用旅客問卷調(diào)查的方法進行候車廳聲環(huán)境質(zhì)量的主觀評價,并對其中2個典型候車廳采取現(xiàn)場測量的方法進行聲場參數(shù)的客觀評價,并深入分析主觀評價結(jié)果和客觀聲場參數(shù)間的關(guān)系。結(jié)果表明:旅客對聲環(huán)境滿意度、聲環(huán)境舒適度與旅客所處環(huán)境的安靜程度、公共廣播系統(tǒng)的播音清晰度具有顯著相關(guān)性;人群噪聲是造成候車廳環(huán)境噪聲的主要噪聲源,而且隨著公共廣播系統(tǒng)播音聲級的提高,人群噪聲有提高的傾向;單純增加公共廣播系統(tǒng)播音聲級與環(huán)境噪聲級之差(S/N)對提高播音清晰度的效果不明顯;提高候車廳內(nèi)公共廣播系統(tǒng)的播音清晰度,需要綜合考慮公共廣播的選型和布置方式、候車廳的建筑聲學(xué)特性、S/N等因素。
[Abstract]:Taking the viaduct of 8 newly built high-speed railway stations in China as the research object, the method of passenger questionnaire is used to evaluate the acoustic environment quality of the waiting rooms. Two typical waiting rooms are evaluated objectively with the method of field measurement, and the relationship between subjective evaluation results and objective sound field parameters is analyzed in depth. The results show that the satisfaction of the passengers to the sound environment, the comfort of the sound environment and the quiet degree of the environment in which the passengers live, and the broadcasting clarity of the public broadcasting system have a significant correlation; Crowd noise is the main noise source of waiting room environment noise, and with the increase of the sound level of public broadcasting system, the crowd noise tends to increase; Simply increasing the difference between sound level and ambient noise level (S / N) of public broadcasting system is not obvious. In order to improve the broadcasting clarity of the public broadcasting system in the waiting room, it is necessary to consider the selection and layout of the public broadcast, the building acoustics of the waiting room and the S / N factor.
