In order to solve the problem of traffic noise and shock interference,the vibration isolation and sound insula-tion reconstruction project of the concert hall in Capital Normal University has been implemented adopting the"room in room"structure.In the reconstruction practice,the difficulties such as the variety of restrictions in structural changes,vibra-tion isolation and sound insulation have been overcome,and improvement measures for the floating floor,sound insulation wall,resilient suspend ceiling,sound insulation doors and windows are adopted systematically.The inner acoustic environ-ment of the concert hall has been significantly improved after the renovation project,and the expected goal has been achieved.The recommended measures have provided a reference for the reconstruction practice of small and medium-sized concert halls with similar volumes.
