A city structure modification of the past is disregard for harmony with city constitution, the balance with perimeter etc. and is made by development process for division.
So, it was created much edge component.
The most of edge component created by that way keep up its peculiarities as limiting specific region but, obstruct continual urban development by breaking interchange with other region. A typical example is soundproofing walls.
The most of our soundproofing walls have the similar shape as metal, concrete structure and is recognize uniformity pattern to the user. So, it bores the user and has the function of only noise reduction.
Soundproofing walls arrest noise pollution come from the road and make comfortable urban environment, but, it is recognized as block factor of fine view even if it has large part of urban view as scale is big and high.
On this study, we got the conclusion as follows as fixing relativity and actual data to submit the method which soundproofing walls change from edge character to structure to do mutual communication.
Edge is divided by discontinuation of edge, communication of edge, negotiation of edge and soundproofing walls by physical edge factor is divided by interception, penetration, compositeness.
The change of each factor act on the important factor to improve urban image and we should design as considering various character of edge and visual shape change of soundproofing walls.
The improvement of urban image by organic plan will give the possibility of communication with already made edge and soundproofing walls.
