| summary |
Adaptability is an essential principle for space multifunctionality. Given that different purposes set different acoustic requirements, adapting one space to different uses is a challenge. Thus, the paper presents a design proposal for a kinetic suspended ceiling made of canvas membrane, implemented in the test performance hall. Such a design aims to improve the control of the reverberation time in the hall. The kinetic structure is divided into panels with the possibility of changing the position in height and rotation. The panels' rotation leads to the structure's unfolding, which leads to the acoustic joining of the hall space with the ceiling interspace, and the diffuse reflection of sound.
Experimental modeling simulation using the Odeon software tool and numerical calculation using Sabin's equation is applied for the research. The research was carried out in two phases. In the first phase, a software model examined the influence of the rotation angle from 0° (flat ceiling) to 90° (completely open ceiling) on the reverberation time. In the second phase, through a comparative analysis of the test model with an implemented suspended ceiling at different heights, the influence of the position of the ceiling in height in combination with the panel rotation was simultaneously examined. The study results in a new approach to the design of folding structures with the possibility of simple installation in existing spaces of performance halls and knowledge of how this type of structure can enable the control of the reverberation time in the hall. |
