Abstract:

Based on the characteristics of acoustic environment and existing residential buildings around airport, the key technologies of sound-insulation reconstruction for the existing residential buildings combined with the actual engineering case are analyzed, which are considering the requirements of residential indoor acoustic environment and building structure safety. The key steps include the sound insulation performance test and the selection of the entrance door and window, structure reinforcement of the balcony and comprehensive renovation of the residential environment. According to the indoor noise measurementresult and the Post Occupancy Evaluation after the reconstruction, the indoor noise meets the limit requirements and the comfort of the living environment have been greatly improved. Therefore the proposed sound-insulation reconstruction technologies can provide as the reference for the similar projects.
