Space_01 Atelier Space HIL G75

The analysed space is an atelier studio measuring approximately 8 × 16 m with a ceiling height of about 4 m, accommodating around 30 architecture students. The room supports multiple modes of occupation, including individual-focused work, small group discussions, and collaborative model making, producing a dynamic acoustic environment with fluctuating sound sources.

The studio is a fully enclosed space characterized by predominantly hard and reflective surfaces. The floor is finished in polished terrazzo, which has a high sound reflection coefficient and contributes minimally to sound absorption. Two sides of the room are composed of glass partitions, while another side includes metal panel partitions, both of which are acoustically reflective materials that tend to promote specular reflections rather than absorption.
Below is an audio of when the space is used and how it sounds:

Despite the large volume of the room, the perceived reverberation time (2 sec) appears relatively short. Speech does not propagate strongly across the space, and the overall sound field feels acoustically contained or “boxy.” No sound is amplified by the reflections, and the noise feels boxy. I guess that the ceiling lined with perforated metal units is what helps absorb most of the reflections.

Space_02 Bridge Between Two HIL Blocks

This space is a bridge that connects two separate blocks of the HIL building. This is often used in transit, meaning no sounds from paused sources. It being a semi-open space allows a lot of background sound from the surroundings to be heard.

The floor is concrete blocks, and the ceiling is clad with a metal GI sheet. Both these reflective materials help produce a reverb. There is a slight flutter that occurs when clapping. The reverberation sounds clinky, sort of like a metallic ring to it. At a certain distance from the opposite door, I was able to hear an echo and flutter as well.
