Audio Visual Relationship Between Sound And Scenery Of Ancient Towns In The Context Of Culture And Tourism

With the development of new urbanization in China,the city spread and expand,people’s memory of tradition and nature gradually fade,instead of the standing of the impeccable high-rise buildings and the apathy feelings.People who live in cities for a long time want nature and peace,and expect humanity and feelings.Therefore,it is very important to build an ancient town environment with local identity and environmental belonging based on the importance of human emotional experience.However,the sustainable tourism development of ancient towns is becoming more and more serious.The overload of people and modern life bring the environmental burden of the ancient town,but also add environmental noise and loss of characteristic sound.The sound environment management and protection should be strengthened for scenic spots and other areas.Therefore,the noise and original ecological sound protection problems closely related to the health of tourists and residents should not be ignored.The research takes the sound scene types of Sanhe ancient town as the starting point,conducts the preliminary investigation and sampling of sound scene data.Through the construction of the characteristics of the spatial sound field,the main component analysis is carried out and cluster analysis is carried out.The conclusion is "monotonous sound scenic area dominated by active sound","active sound dominated sound scene publicity area","traffic sound dominated noise control area" There are seven categories,namely,the sound scene rich area with natural sound as background sound,the talk area of the sound scene with the natural sound as the background sound,the construction area of the active sound dominated sound scene and the special area of the sound scene dominated by the active sound.Secondly,the overall perception description and the evaluation of the preference of the source are carried out.Based on the SD questionnaire data,the paper evaluates the importance of visual environment and analyzes the correlation.Through the comparative study of different spatial types,the similarity and difference of sound source preference and acoustic environment expectation are studied,which shows that natural space is more expected to be natural and society is more expected in artificial space Sex.Thirdly,through the analysis of EEG experiment,we can capture people’s physiological perception of some active sound landscape in Sanhe ancient town.The average and standard deviation of α wave generation of different experimenters at different electrodes were obtained by Fourier transform method.The data rules were compared and analyzed to explore the physiological perception preference rules of different visual environment categories and different combination of audio-visual environment.Finally,based on the results obtained in the previous study,the paper puts forward the optimization strategy of ancient town environment under the interaction of audio-visual.This paper takes the tourism town with local cultural characteristics and rich natural resources as the research object,takes sound scene as the starting point,deeply analyzes the value of audio-visual environment resources,and makes beneficial thinking on the user’s sound scene evaluation;based on a series of investigation and experimental data quantitative analysis,it complements the basic data of sound scene evaluation in ancient town,and tries to explore the universal applicability Conclusion of sexual significance;the application of public perception evaluation provides support for the establishment of multi-dimensional environmental evaluation system,and also provides experience accumulation for designers and managers;from the noise level,sound scene provides a more comprehensive,active and targeted judgment basis for environmental noise through the interaction between environment and sound,and provides a more comprehensive,active and targeted judgment basis for relevant planning,environmental improvement,noise prevention and control,etc It provides technical methods reference,which has practical significance.
