Geometric absorbers and diffusers shape the space, controlling how sound travels, reflects and dissipates. /CGTN

Used for testing and research, the space reveals how sound can be engineered, measured and experienced through design. /CGTN

Looking more like a minimalist interior design or some sort of art installation, this is in fact a highly specialized acoustic environment. The room is filled with wedge-shaped absorbers and curved diffusers, designed to control how sound propagates, reflects and decays – often creating near-anechoic or highly-controlled sound fields.

The wedge structures absorb sound through repeated internal reflections, while spherical and curved surfaces scatter sound waves to simulate complex acoustic environments. The suspended mesh floor minimizes reflections from below, ensuring accurate measurements.

At China Sound Valley, such spaces are widely used for speech recognition, noise reduction, and audio device testing. Their form is not driven by aesthetics, but by acoustic principles.
