Abstract

There is a great demand in multipurpose elements design for use adaptation. This in turn requires great flexibility in design strategies, as well as a wider spectrum of space settings to achieve the required environment that special activities imply. Acoustics is an essential factor influencing cognitive acts and behavior as well as on the extreme end the physical wellbeing inside a space. The complexity of this constrain is fueled up by the extended geometric dimensions of multipurpose halls, making acoustic adequateness a great concern, that could not easily be achieved for each purpose. To achieve a performance oriented acoustic environment, various parametric shaped false ceilings based on origami folded notion are simulated. These parigamic shapes are able to fold and unfold forming an oribotic structure, and changing the mutual acoustic environment according to the geometric shapes position and its changing exposed surface areas. The mobility of the facets in the parigamic surface can stretch up the range from a complete plain surface to an unfolded element where a considerable amount of absorption is added to the space. The behavior of the parigamic shapes are being modeled employing a ray tracing computer simulation package for various shapes topology. Results revealed a divergence of results that is caused by the folded facets to shorten the mean free path thus introducing more reflections and consequently quicker decay curves.
