Abstract
The site conditions around the drainpipe in the existing apartment houses were very different from the original construction conditions, and each house was in poor condition due to repair and damage. If the conditions around the drain pipe are good, the reduction in the application of the drain cover is up to 16.8 dBA. The characteristics of drainage noise in the lower and upper floors showed that the peak level of the noise in lower floors was lower than that of the upper floors; however, the duration of drainage noise was longer than that of the upper floors, indicating that the lower floors were significantly affected by balcony drainage noise compared to the upper floors. As most residents positively judge the performance and effect of the balcony drain cover and their willingness to purchase the drain cover is very positive, they believe that the promotion and distribution of the drain cover will significantly help in reducing the balcony drainage noise in existing apartments.
