SUSTAINABLE ACOUSTIC WALL INSTALLATION

Overview

This project enhances meeting spaces within RMIT University’s Design Hub by creating an environment that improves both acoustic performance and user experience.

​

Problem

Existing workspaces allowed sound to leak, disrupting nearby activities. The challenge was to confine sound within a designated meeting space while maintaining a visually engaging and user-friendly design.

​

Research and Insights

User experience, acoustics, sustainability, and material behavior were central to the research. Cardboard tubes were selected for their sustainable qualities, geometric flexibility, and effective sound reflection and absorption properties.

​

Solution

The final installation transforms the brief into an immersive acoustic environment that contains sound while enriching the user experience. Made from sustainable cardboard tubes, the structure expresses sound through its form, offering both visual interest and acoustic performance. The result is a meeting space that is functional, sustainable, economical, and recyclable, while also delivering a distinct spatial and sensory experience that elevates everyday interactions.
