At Ecolandscape Studio, we view landscape design as a multilayered system of environmental perception, where sound is just as important a design material as topography, light, or vegetation. In the conditions of a modern city, acoustic load has become a constant environmental factor, and for this reason the acoustic landscape is emerging as a separate direction in sustainable spatial design.
What is an acoustic landscape
An acoustic landscape is a landscape design system aimed at forming a controlled sound environment using natural and architectural elements.
Its key idea is that sound should not be seen only as noise that must be eliminated. Instead, it becomes part of the spatial experience and can be redistributed, softened, or transformed into a more comfortable acoustic structure.
Unlike engineering-based noise protection solutions that function as physical barriers, the acoustic landscape works with human perception, shaping a natural and emotionally stable sound background.
How an acoustic landscape works
Sound in open space follows the laws of wave propagation, and these properties are used in design.
Topography forms the basic acoustic structure of a site. Changes in elevation, embankments, and depressions create acoustic shadow zones where noise levels are significantly reduced. This is one of the most effective natural ways of controlling sound fields.
Vegetation performs several functions at once. Dense plantings of shrubs and trees partially absorb sound energy, but more importantly, they disrupt the direct propagation of noise, making it less sharp and less structured. Multi-layered green masses work best, especially when combining different types of foliage and planting densities.
Water acts as an acoustic stabilizer. Streams, cascades, and reflective ponds create a uniform natural sound that masks irregular urban noise. This is not just a decorative element but a tool for shaping a sound background that the brain perceives as safe and predictable.
Surface materials influence sound reflection. Hard, smooth surfaces intensify reflections and can create acoustic harshness, while porous, natural, and textured materials reduce echo and make the environment softer. It is important to consider not only the type of material but also its spatial placement.
Spatial composition also plays a significant role: narrow corridors can amplify sound, while open, dispersed areas can diffuse it. Therefore, an acoustic landscape is always designed as a system of interconnected spaces rather than a set of isolated elements.
Additional acoustic strategies in landscape design
Beyond basic natural components, more subtle methods of sound control are used in acoustic landscape design.
One of them is the creation of “sound buffer zones” transitional spaces between noise sources and relaxation areas. These can be sequences of plantings, hills, and water elements that gradually reduce sound intensity.
Another approach is sound masking. Instead of fully suppressing noise, it is overlapped with more pleasant and stable sound layers such as water, wind in vegetation, or natural ambient sounds.
Seasonality is also important. In summer, vegetation works at maximum efficiency, while in winter acoustic protection may decrease, requiring compensatory design solutions such as topography and material selection.
Psychoacoustics and spatial perception
The acoustic landscape is based not only on the physics of sound but also on psychoacoustics how humans perceive sound environments.
The human brain is much more sensitive to irregular and sharp sounds than to uniform background noise. This is why water features or wind in vegetation are perceived as comfortable, even if the overall sound level remains noticeable.
The goal is not only to reduce decibels but to change the structure of the sound field. This directly affects the feeling of safety, relaxation, and the willingness to stay in a space for longer periods.
Where acoustic landscapes are used
This approach is most effective in dense urban environments with high building density and transport loads. These include residential districts near highways, public spaces, parks, and inner courtyards.
In private architecture, it is used to create secluded gardens where separation from external noise and a more intimate atmosphere are important.
Another important application is therapeutic spaces. In sanatoriums, rehabilitation centers, and healing gardens, the acoustic environment becomes part of the therapeutic process, influencing the nervous system and recovery speed.
Limitations of the approach
The acoustic landscape has its limits of effectiveness. In cases of extremely high noise levels, it cannot replace engineered noise barriers and works only in combination with them.
It also requires sufficient space for shaping terrain and multilayer planting systems. In dense urban environments, its effect may be partial.
Another key point is system thinking. Using isolated elements without a comprehensive acoustic analysis of the site does not produce stable results.
In the practice of Ecolandscape Studio, acoustics is considered one of the key layers of landscape design. We work with it on the same level as ecology, topography, and the spatial structure of light.
As Martin Palma, founder and CEO of Ecolandscape Studio, notes, sound design is one of the most underestimated yet critically important aspects of spatial design. In his experience, even a visually perfect space can feel uncomfortable if its acoustic structure has not been properly designed.
The acoustic landscape is a modern tool for creating high-quality environments that goes beyond visual design.
At Ecolandscape Studio, we see it as part of a comprehensive approach to spatial design, where sound becomes a controllable element of landscape architecture.
This approach not only reduces noise but also helps form a new urban acoustic culture, where the sound environment becomes natural, stable, and comfortable for humans.
