Immersive Sound Installation at Oulu Cathedral Uses FRB Data from CHIME Telescope

"The Logos": A Cosmic Symphony in Stone

Over 4,000 cosmic signals are being transformed into spatial audio within the walls of a historic Finnish cathedral, in one of the most ambitious artistic sonifications of fast radio bursts ever attempted.

The Installation

A new immersive sound installation, "The Logos," opened at Oulu Cathedral in Finland on April 4. The work translates data from fast radio bursts (FRBs)—detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope—into a dynamic, spatial audio experience.

Who Is Behind It

The project is led by artist and creative technologist Andrew Melchior, collaborating with MIT astrophysicist Kiyoshi Masui, philosopher Timothy Morton, and cathedral dean Satu Saarinen. The installation is part of the Oulu2026 European Capital of Culture program and the Lumo Art and Tech Festival.

How It Works

  • The Cathedral as an Instrument: Built in 1832, the cathedral’s stone surfaces and natural acoustics give physical presence to the otherwise intangible signals.
  • Daily Performance: Each day at noon, a one-hour procedural composition derived from FRB data fills the space.
  • The Source: Some FRBs are singular, explosive events; others repeat from unknown sources across the cosmos.

A Sensory Translation

Astrophysicist Kiyoshi Masui described the sonic effect:

"The fast flashes will echo as snare-like beats bouncing through the cathedral. The sweeping dispersion of the signal creates harmonies between high and low tones."

What Are FRBs?

Fast radio bursts are energetic flashes lasting only milliseconds, originating in distant galaxies. The CHIME telescope is a leading detector of these enigmatic signals. The Logos represents one of the most extensive artistic treatments of this data to date.

Run and Significance

The installation runs through April 2027, coinciding with Oulu Cathedral's 250th anniversary. It offers visitors a rare chance to hear the universe—not as a scientific visualization, but as a live, spatial composition echoing through stone and time.
