Application Of Noise Map In Organic Renewal Of The Non-protected Districts

The organic renewal of non-protected districts is an important means for urban stock optimization. With the gradual implementation of the high street density, small block size planning policy, the problem of internal traffic noise in non-protected districts has become increasingly prominent. In the past, most of the research on street acoustic environment focused on the noise control and the direction of soundscape in historic districts. There was less research on the large number of non-protected districts in cities. The acoustic environment of non-protected districts has a close relationship with its vitality. This article takes Xigu District of Tianjin as an example, with the perspective of factor analysis, and uses Cadna/A noise map software to use soundscape objective + noise map model to study the interaction between the acoustic environment and the spatial form of non-protected districts, and to evaluate the non-protected district renewing plans. It draws simulation conclusions from the spatial and temporal distribution of noise, comfort of acoustic environment, and optimal district mod ,and puts forward the ways and methods of the authenticity protection.
