Sound installation “Soundlapse” at Museum in Valdivia

The sound installation Soundlapse: Landscapes in Transformation was presented at the Heritage Interpretation Center De Todas las Aguas del Mundo between October 20 and 24. The work was experienced by more than 320 visitors, who took part in the immersive event during both the daytime sessions and the Night of the Museums on Friday, October 24.

The piece was created as a collaborative project by Felipe Otondo, Leonardo Santos, and Francisco Ríos Anderson, bringing together artistic, scientific, and technical approaches to explore the acoustic diversity of southern Chile’s aquatic environments.

Soundlapse: Paisajes sonoros en transformación

An immersive sound installation that invites audiences to explore how sound reveals changes in the natural landscape. The work is based on 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 environments.

Soundlapse is a project developed since 2015 by researchers and artists affiliated with the Acoustics Institute at the Austral University of Chile. Over the course of a decade, the team has systematically recorded wetlands and natural environments in southern Chile to monitor how climate, biodiversity, and human activity shape and transform acoustic landscapes.

Just as a visual time-lapse accelerates the passage of time, this installation condenses years of environmental change into a continuous sound composition. The result allows listeners to experience —through sound— the evolving dynamics of a coastal territory and its ecological transformations.
