Research On The Influence Of Soundscape Elements Of Urban Traffic Plaza On The Perception Of Soundscape

The urban traffic plaza takes an island-like transportation hub as its core function and exists as an open activity space.It is an indispensable functional space for the city and provides urban residents with healthy living environment resources.However,with the rapid development of cities,noise pollution has increasingly become a challenge to urban open space.This paper uses soundscape related theories and technical methods,using on-site soundscape surveys and laboratory panoramic soundscape experience combined with human factors technology experimental methods,taking Shenyang City Traffic Plaza—Zhongshan Plaza as a typical object to carry out empirical research to explore urban traffic Square soundscape elements and their influence on the perception of soundscape.Through the combination of acoustic measurement and design and distribution of interview questionnaires,the soundscape survey of Zhongshan Square was carried out to obtain acoustic data and soundscape perception data.The current situation of the acoustic environment of the traffic square was analyzed through the above data,and the significance of the sound source perception,The relationship between physical acoustic indicators,individual differences and soundscape perception is statistically analyzed,and the influencing factors and laws of soundscape perception in traffic squares are obtained.It is found that the change of sound pressure level and the type of sound source have a significant impact on the perception of the soundscape,which are the two major factors affecting the perception of the soundscape in traffic squares.Further explore the effects of sound pressure level and sound source type on the perception of soundscape.Innovatively realized the construction of a panoramic audio and video soundscape reproduction experimental platform,and synchronized measurement with the human factors experimental platform.The experimental data collection uses the subjective and objective measurement technology that combines the soundscape perception scale and the measurement of human factors physiological indicators.After statistical analysis,the sound pressure level and the introduction of underwater sound masking have been proposed from the perspectives of soundscape perception and physiological indicators to affect the quality of soundscape perception: a decrease in soundscape sound pressure level in traffic squares will have a positive effect on the quality of soundscape perception.Influence,the introduction of natural sound will also have a positive effect,reduce the perception of negative emotions,and play a positive effect on the user’s physiology and psychology.Finally,strategies are proposed based on noise control and soundscape resource optimization,including planning and management of noise prevention and control,sound insulation and noise reduction,and hearing preference optimization,natural soundscape optimization,independent soundscape design,etc.,to provide design for urban traffic square designers Suggest.The main innovations of this subject: the realization of the construction of a panoramic soundscape experimental platform,the use of panoramic soundscape audio and video as stimulus materials for experimental research,the soundscape reproduction is more realistic;the quantitative analysis of human factors physiological measurement technology is combined in the experiment,and The research conclusions obtained hope to provide the designer with a theoretical basis,and from the perspective of the acoustic soundscape,it is expected to provide suggestions and strategies for optimizing the sound environment quality of urban traffic squares.The urban traffic square takes the round-island-style traffic management as its core function and exists as an open activity space.It is an indispensable functional space for the city and should provide a healthy living environment for urban residents.However,with the rapid development of national cities,noise pollution has increasingly become a major challenge for urban open space.This article relies on the academic vision of soundscape,from the perspective of users in urban traffic squares,soundscape investigation and human factors experimental techniques.Taking Zhongshan Square as a typical research object,studies the soundscape elements of urban traffic square and their influence on soundscape perception.
