Nevertheless,or exactly for that reason,it is the place that is still full of extreme neglect and even hostility toward the noise's aesthetic and political possibilities ,only the lives of every samll and minor activity that has its own aural qualities could not be accumulated and sustained here;the condition for listening to the sound of the collectives of the 'small poeple' and the 'tiny machines',under or maybe beyond the threshold of audibility ,dosesn't seem to be secured sufficiently.surely,this kind of problem is not confined in the particular locality like seoul,or south korea.anyway,this tension and the sense of the absence of condition,together,have been the main source of the two koren resident noise-making.

然而，或许更是因为，这是一个对噪音美学与政治的可能性充满轻蔑与敌视的地方，在这里，那些有自身听感氛围与质量的小众活动不能够集聚起来并很好的持续下去；对於那些倾心于此类音乐并集合在一起的"弱小个体"们和那些"微型机器"，必然是早就远离或超越了肤浅的旋律性和可听性的门槛，看起来并不能稳定地被安置，当然，此类问题不只被局限在一个小的局部，首尔，韩国，无论在哪，这一切产生的张力连同其状况本身，反复地显现在我们眼前，交织在一起，构成了两个韩国人创作原生噪音的来源。
