Successful presentation of a sound installation at a museum in Valdivia

The sound installation Soundlapse: Soundscapes in Transformation was presented at the Centro de Interpretación Patrimonial De Todas las Aguas del Mundo in Valdivia between October 20 and 24. The work was visited by more than 320 people, who took part in the experience during regular opening hours as well as during the Night of the Museums event held on Friday, October 24.

The installation explored immersive listening to natural soundscapes from southern Chile, using multichannel spatial audio to highlight temporal, ecological, and perceptual transformations in wetlands, forests, and coastal environments. Designed as both an artistic and research-driven work, the installation also contributed to ongoing investigations into immersive sound, listening context, and audience perception.

The work was created as a collaboration between Felipe Otondo, Leonardo Santos, and Francisco Ríos Anderson.

Soundlapse: Soundscapes in Transformation

An immersive sound installation that invites audiences to explore how sound reveals changes in the natural landscape. The work is based on field recordings made at Playa Grande in Curiñanco and on psychoacoustic experiments using 3D audio technologies (Ambisonics), designed to investigate how people perceive sonic immersion in multichannel listening environments. Soundlapse is a project developed since 2015 by researchers and artists associated with the Institute of Acoustics at the Universidad Austral de Chile. Over the course of a decade, the team has systematically documented wetlands and natural environments in southern Chile to monitor how climate, biodiversity, and human activity shape and transform acoustic landscapes. Much like a visual time-lapse accelerates the passage of time, this installation condenses years of environmental change into a continuous sonic montage, allowing listeners to experience the evolution of a coastal territory and its ecological dynamics through sound.
