The acoustic behaviour of multilayer wallpaper made from hemp stalk and rice straw is investigated in this study. The work was developed from a broader study on bio-based interior materials, but the present paper focuses on acoustic performance. The proposed wallpaper consists of a porous core layer based on hemp–straw mixtures and a surface layer made of Xuan paper, jute fabric, and dried...

Edgard Varèse described music as “organized sound.” and Iannis Xenakis, in collaboration with Le Corbusier, developed spatial systems in which sound, form, and movement are composed as a single environment. Building on this framework and lineage, Ninefold treats composition as an organizational system where architecture, music, and fabrication converge through relational interactions among...

Stagger is an experimental acoustic surface that proposes to expand the role of furniture in architecture. Vintage Haworth stackable chairs from the 1990s, which were designed to have minimal footprint when not in use, were repurposed to intentionally clad a wall in an acoustically beneficial and visually engaging arrangement. The chairs retain their original purpose, and are removed from the...

Within architecture’s inherently multisensory framework, contemporary acoustic design often remains secondary, addressed through applied absorptive treatments rather than embedded spatial strategies. Despite advances in computational tools, most built environments still rely on standardized reflective materials like concrete, glass, plywood, resulting in a limited, binary understanding of...

The advancement of 3D printing of ceramic materials has opened several research lines regarding the fabrication of acoustic porous building materials for a range of applications. To this end, this paper presents a first proof-of-concept experimental characterization of sound-absorbing panels produced via Viscous Thread Printing (VTP), a previously unexplored fabrication method for room...

Locally resonant metamaterials can be designed to achieve higher absorption compared to conventional porous materials. The sound absorption performance of both kinds of structures is strongly reduced when incident waves impinge them at angles different from normal incidence. Among other metamaterials alternatives, inclined wiremesh gratings exhibit broadband and omnidirectional absorption in...

Diffusion is a key, but often underweighted characteristic of acoustic surface design in interior spaces. While absorption and reflection dominate practical acoustic treatment, diffusion governs the uniformity of sound propagation, particularly in larger auditoriums and multipurpose halls. Algorithmically generated diffusive geometries deliver calculable scattering performance but are often...

The 3D printed architecture together with the expanding capabilities of contemporary parametric design platforms has opened remarkable opportunities to complex geometric explorations and function integration. In this context, perceptual investigations result important to go beyond single parameter objective values and highlight the benefits of design solutions allowing for a more optimized use...
