| Summary: | This paper describes a preliminary investigation on the possible use of deformable
origamic shapes as a technique to provide adjustable acoustical performance in multi-purpose hall.
The term ‘deformable’ means that the origamic shape undergoes deformation which automatically
resulted into the change of its geometrical configurations. The experimental investigation has been
carried out on three types of origamic shapes with several geometrical configurations. The
measurement tests were conducted in a reverberation room and in accordance to ISO 354:2003
Measurement of Sound Absorption Coefficients in a Reverberation Room. Findings from the
preliminary investigation show good trends indicating that the origamic shapes have the capability
of adjusting the sound absorption coefficients by varying their geometrical configurations.
Following those results, future works with details investigation will be undertaken as to validate the
preliminary results. |
