The Acoustic Benefits of Moss Walls

Traditional soundproofing often prioritizes function over form. But preserved moss changes the game. Its intricate structure — soft, porous, and irregular — naturally traps sound waves and diffuses echoes. This makes it an ideal choice for spaces like offices, hotels, restaurants, and lobbies where noise control meets aesthetics.

A study conducted by CARE CEDIA at the University of Liège (Belgium), commissioned by Moss Art London, confirmed the impressive acoustic absorption performance of preserved moss.

“The laboratory provided us with detailed reports showing the undeniable sound-reducing qualities of the natural moss,” the company stated.

The tests followed the ISO 11654:1997 standard, measuring sound absorption coefficients in a controlled 10m² setup for each moss type. The results showed that preserved moss performs exceptionally well at reducing reverberation, often comparable to or exceeding traditional acoustic panels — proving that design and function don’t have to compete.

From moss acoustic panels to acoustic moss wall installations, designers are increasingly using greenery to soften soundscapes. Beyond the technical advantages, moss walls introduce a biophilic quality that industrial materials can’t replicate.

“Moss panels offer both sound dampening and psychological calm,” says interior designer Claudia Renner, known for her work in hospitality spaces. “They absorb more than just sound — they absorb stress.”

Architectural studies also indicate that adding greenery and natural textures can reduce perceived noise discomfort and enhance concentration — effects especially valuable in open offices and hospitality venues.

Preserved moss requires no watering, sunlight, or trimming. Once installed, it remains soft, vibrant, and acoustically effective for years. For designers seeking sustainable acoustic panels, moss offers the rare combination of low maintenance, natural texture, and measurable performance.

Depending on moss type and density, absorption coefficients (α) can reach values between 0.55 and 0.90, particularly for denser mosses such as Pole or Bun moss. These results align closely with findings from Moss Art London’s CARE CEDIA tests, confirming moss’s ability to absorb sound in the mid- to high-frequency range where human speech typically resonates.

Unlike synthetic acoustic materials, moss walls do more than absorb sound — they add a living softness to a space. Whether used as acoustic moss wall panels in a conference room or a preserved moss wall art installation in a hotel lobby, they make quiet feel intentional.

As Moss Art London’s findings reveal, “preserved mosses are increasingly seen as the perfect answer to this problem — sometimes considered better than even traditional industrial solutions.”
