Data sonification makes data listenable.
More than a method for translating numbers into sound, it gives abstract systems a temporal, spatial and emotional form.
Climate change, migration, language, swarm behaviour or environmental conditions can become audible as rhythm, density, movement, tension or change.
In exhibitions and installations, this allows visitors to encounter data not only as information, but as something that unfolds around them.
Data sonification describes the translation of data into sound.
Values, patterns and relationships within a dataset can shape musical and sonic parameters such as rhythm, pitch, harmony, density, texture, dynamics or spatial movement.
The result is not a chart made audible. It is a listening situation in which change can be perceived over time.
This is especially relevant when data describes processes that are difficult to see directly: ecological transformation, collective movement, emotional intensity, linguistic patterns or behaviour within a system.
Data is often treated as something to be read.
Sound allows it to be experienced differently. A pattern can repeat, shift, accumulate or disappear. A small change can become a transition. A large system can become a rhythm that visitors follow physically.
In spatial contexts, sonification can work together with image, light, architecture and interaction. It can support understanding without turning the experience into explanation.
The value lies in making the invisible perceptible, while keeping the data connected to atmosphere, movement and meaning.
The translation from data to sound can take different forms, depending on the role the data should play in the experience.
Data-driven composition
Values influence musical structure, rhythm, tempo, harmony, pitch, density or duration. The data becomes part of the composition itself.
Spatial sonification
Sound appears in different zones, moves through a room, changes with position or creates relationships between places. Data becomes part of how the space is perceived.
Generative behaviour
A sound system follows rules, live conditions or changing input, creating variation over time. Data shapes how the system behaves rather than producing one fixed result.
Interactive sonification
Visitor movement, gestures or choices become audible. This makes a system understandable through action and feedback.
Data sonification is closely connected to sound scenography.
Sonification defines how data becomes sound. Sound scenography defines how that sound belongs to an experience: where it is heard, how it unfolds, how it relates to space, media, movement and attention.
In an exhibition, data should not simply be present. It should have a role.
It may guide visitors through a complex subject, give emotional weight to a hidden process, or connect individual moments into a larger spatial narrative.
Related practices include sound scenography, generative sound, spatial audio and interactive sound.
Examples of data sonification in our work include:
Emotional and linguistic data from political speech becomes sound and light. The installation reveals how language carries affect, intensity and distortion, turning speech analysis into a spatial audiovisual experience.
Climate data reshapes Vivaldi's Four Seasons. Environmental datasets influence timing, musical structure and material, making ecological change audible through a familiar musical reference.
Environmental data from the marine research station in Kerteminde becomes the basis for a four-hour multichannel soundscape. The underwater tunnel is shaped by data recorded near the site.
Migration and climate data inform a generative sound work for THE HERDS. Movement, distance and ecological displacement are translated into a living musical system.
River behaviour becomes an audiovisual composition. Machine learning and generative sound translate flow, erosion and sediment patterns into music that changes with the movement of the visual system.
Swarm behaviour shapes an interactive sound environment. Visitor movement and collective patterns influence sonic intensity, alignment and disruption inside the installation.
From there, the sound can be designed as a direct translation, a compositional structure, a spatial system or a generative behaviour.
This work can include data analysis, mapping strategies, composition, spatial audio, interaction design, generative systems and on-site tuning.
The goal is not to sonify everything. The goal is to make the right relationships audible.

What is data sonification?
Data sonification is the translation of data into sound. Values and relationships within a dataset can shape rhythm, pitch, harmony, texture, dynamics or spatial movement.
Why use sound for data?
Sound unfolds over time. It can make change, repetition, intensity and relationships perceptible in a way that complements visualisation.
Where is data sonification used?
Data sonification can be used in exhibitions, installations, research communication, climate narratives, public spaces, interfaces and generative artworks.
Is data sonification always musical?
No. It can be musical, atmospheric, abstract, spatial or functional, depending on the project and the role the data should play.
How does data sonification relate to sound scenography?
Data sonification translates information into sound. Sound scenography places that sound within a spatial and dramaturgical experience, so it becomes part of how visitors perceive and understand the space.
Working with data, systems, or complex information?
We design sound that transforms data into spatial and emotional experience.
