Sound Greenfall: A serenade to plants and humans
Sound Greenfall – literally meaning “cascade of green sounds” – is a transdisciplinary installation merging architecture, bioacoustics, neuroscience, and ecology to propose a new bioacoustic spatial paradigm. Currently presented at the 19th International Architecture Exhibition of La Biennale di Venezia, it emits cascades of calibrated low-frequency sounds able to promote plant growth and human neurophysiological well-being. Nested in a blooming garden (or an artificial capsule-garden), visitors can lean the ear to its reflective structure to immerse themselves in a cascade of sound waves while being enveloped by the rich multisensory environment of the garden to foster restoration and connection.
The installation cultivates a minimal and elegant aesthetic. The metal sheets are made of embossed mirror stainless steel, a material with a rhythmic pattern, which alludes to cascading waves of sound, fragments the environment, the sky, the clouds, the greenery, the flowers, and even the people, transforming everything into sprinkles of colours, petals of skin, and mystical landscapes. With its reflections and appearance changing according to the environment and visitors’ perspectives, the installation harmonises playfully with the landscape.
The project draws on pioneering research conducted with scientists from CNR-Florence and the University of Florence (plant bioacoustics), and from Cambridge and Harvard (neuroscience). Plants of Mentha Pulegium exposed to specific low-frequency sounds showed improved growth and adaptability; in parallel, EEG clinical analyses on humans showed enhanced relaxation and cognitive restoration, and overall well-being. These findings open the path for new forms of regenerative and scientific-driven architecture rooted in a new “vibrational ecology” across species.
The project responds to the ecological crisis, seeking to bridge the theoretical and emotional gap between humans and nature. Rooted in the critical lineage that challenges oculocentric design, Sound Greenfall recasts design as a resonant interface: a threshold where bodies, plants, and atmospheres co-vibrate through sound as spatial agency and listening as a design act to reawaken the empathic senses. Modular and adaptable, it can be expanded across geographies and formats. Here Sound Greenfall is a sound sculpture that is also a scientific device — a reflective, vibrant, resonant element to be placed in both interior and exterior settings, functioning as a vibrant speaker that is meant to change its environment, transform our biology, tune us in with nature, and offer a moment of breath from the hectic pace of life. Envisioning a movement that extends the research to multitudes of vital plant species and cross-cultural landscapes, the project aligns with regenerative goals, positioning art and architecture as mediums for ecological intelligence, interconnection, and well-being.
