Balcony drainage noise in existing apartments is one of the facility noises subject to civil petition, next to the floor impact sound for residents. Newly constructed apartment houses have separate discharge systems for rainwater and drainage, thus, the drainage sounds of upper house are blocked by the lower house. However, as the structure of balcony drainpipes of apartments built before 2006 incorporate rainwater and drainage, residents are continuously complaining about the balcony drainage sounds. To reduce existing apartment balcony drainage noise, studies have been conducted in which drain covers were constructed at the location of maximum noise as a measure to identify the maximum location of drainage noise among the drainage pipes. Based on the results of previous researches, several additional components are designed and created that can be added to existing commercial products and are easy to apply to existing drainage pipes. Furthermore, they have been designed to be easy to detach and maintain, and were precisely manufactured and applied to actual apartments for performance testing. As a result, if a plastic member with a thickness of 5 mm is added to an existing commercial product, the reduction is estimated to be around 13 dB. This can reduce drainage noise in daily life to approximately 45 dB, which will help create a quiet living environment for existing apartment inhabitants.
