A Study On The Soundscape Design Of Public Space In Coastal Area

Urban coastal area is an ideal place for people’s leisure and entertainment activities.The sound of sea water is a major feature of the coastal area,and is a unique sound resource in the coastal area.At present,there is a lack of effective classification and evaluation system and standard for the acoustic environment in the coastal area.Acoustic landscape is a new subject,which mainly studies the relationship between environment,human and sound,and is superior to traditional architectural acoustics.Three.The purpose of this study is from the perspective of soundscape,investigated the coastal areas of the sound environment of different categories,summed up the evaluation index of the coastal sound environment and evaluation system,and compare the advantages and disadvantages,characteristics of acoustic environment in coastal area of different categories,to further explore the design methods of shaping the sound landscape of coastal areas.According to the different attributes of the landscape elements,the coastal areas are divided into natural,artificial,semi natural and artificial.Acoustic walks,tidal sound tests,and questionnaires were also performed at three locations.The survey data,the results into the computer,and extract the analysis,the use of SPSS,GIS,Excel,Photoshop and other software will be the results presented in pictures,tables,text,etc..A large amount of research results.There is a great difference in acoustic evaluation between different areas of semi artificial and semi natural coastal areas.Artificial coastal area although the sound level is large but good evaluation.The design level of natural coastal area is small,and has obvious advantages in three acoustic evaluation indexes.23 typical sound factors were extracted to obtain 9 common factors,and the SD method was used to measure people’s attitude towards them.The sound of the marine natural factors,forest insects sound factor,fishing is a favorite fountain sound factor,and independent factor,leisure fishery activities sound sound factors,daily activities factor is that people don’t love sound nor hate,Binhai entertainment factor,the construction of commercial acoustic sound factors are factors people hate the cultural and historical evaluation the sound of the difference.There was no significant correlation between sound preference and its standard deviation.The evaluation of the soundscape is summarized with the degree of comfort,harmony and comfort,and the evaluation of comfort is stable in three dimensions.The coastal environment gives theimpression that it is neither quiet nor lively.The evaluation of comfort is higher than the degree of harmony.Three very significant correlation between the 22 indicators.The types of coastal areas were significantly or very significantly correlated with the three indicators.The design method of natural coastal area is very helpful to improve the evaluation index of coastal sound.People’s satisfaction with the current coastal processing and the three indicators were significantly or very significant correlation.Can people tell the difference between the high tide and the low tide from the sound and the sound is very significant correlation,etc..Conclusion from the results.By changing the influence factors of coastal soundscape evaluation,we can change the degree of comfort,degree of harmony,and improve the quality of coastal landscape.Specific means such as: in the natural coastal area of the original natural sound does not make any changes,the design of some sound devices to collect natural sounds.In the semi artificial and semi natural coastal area,analysis and planning of the background sound,sound information,partition of soundscape,using wood as the sound barrier of coastal areas,arrange the speaker layout,broadcast,broadcast time etc..In the natural coastal area,the design of a simple visual environment to reduce noise interference,etc..
