Under the EU’s Horizon 2020 program, a project called SOUNDCOMB+ (Wall‑integrated Ecologic Sound Absorbing Panel) was initiated (led by IDEE & DESIGN in Austria) to embed acoustic function directly into wall structures, creating a truly integrated wall + sound absorption solution.

Key outcomes achieved between 2018 and 2019 include:

• Use of 100% sustainable materials, with the ability to render arbitrary surface prints (2D / 3D), textures, or patterns, combining acoustic performance with aesthetic flexibility.

• Achieved absorption efficiency in tests exceeding 95% in assembled state, showing particularly strong mid-to-high-frequency response.

• SOUNDCOMB+ is positioned as a structural building element rather than a mere functional panel detached from the structure.

Although this project remains at a prototype / validation stage, its design philosophy has valuable implications for akupanel / advanced acoustic wall panels:

• Integrating absorption layers into the wall structure can save space and enable seamless design

• Custom graphics, patterns, and geometries open up opportunities for product differentiation

• Emphasis on high absorption efficiency, sustainability, and simplified installation represent key directions of competition

If such wall-integrated acoustic products reach industrial-scale production, they may become a benchmark in high-end interior construction.
