7th Forum Acusticum 2014, September 7-12 2014, Krakow, Poland
The city of Christchurch, New Zealand currently lacks performance studios where performers can practice due to the widespread damage caused by the 2011 earthquake. However, there are large areas of vacant lots in the city center where buildings have been removed, but redevelopment work has yet to begin. To solve the problem of the lack of available studio spaces and to take advantage of the available open spaces, a mobile building known as project BeatBox was proposed to be built in one of the available, vacant lots. The mobile building includes three studio spaces as well as office spaces. A stipulation for the building design was that it needed to be possible to disassemble the entire building so that it can be transported to a new site and reconstructed when the original building site is ready to be redeveloped. Additional stipulations included stringent sound insulation requirements between the studios, between the studios and the offices and between the studios and the outside. A novel design for the space was proposed to meet the airborne and impact sound insulation requirements based on prediction models. The final design was a compromise between the acoustic, earthquake, fire and structural requirements. The building design is presented and the measured sound insulation values of the studios are compared versus the original, predicted values.
