start a story about the world of sound in National Forum of Music in Wroclaw
The Main Hall seats 1800 people and includes the parterre, amphitheatre, choir and three balconies. All the NFM halls are acoustically insolated through multiple massive walls, structural breaks, and base building isolation systems. The Main Hall can be thought of a structurally independent building within the NFM buidling, isolated from the rest of the buidling and from sources of noise and vibration from external sources.
