Un Suono in Estinzione (USIE) is an art–science project that integrates acoustic monitoring and scientific analysis of Alpine glaciers. Its goal is to acquire, correlate, and translate audio and environmental data into research outputs, artistic works, and dissemination tools that support the study of climate change.

The project was initiated in 2020 by researcher and sound artist Sergio Maggioni, also known as NEUNAU, and has been developed together with a team of professionals from scientific, artistic, and technical fields.

Phase 1: Data collection campaign on glaciers.

Phase 2: Scientific analysis of the collected data.

Phase 3: Dissemination through artistic works and scientific papers.

The data acquisition system includes 24/7 recordings using microphones, geophones, hydrophones, thermal sensors, and hydro-meteorological instruments installed on the Adamello Glacier.

The data workflow involves continuous acquisition, annotation, filtering, spectral analysis, and correlation with physical parameters. Results include long-term audio–environmental time series, acoustic indicators of melting, and comparable datasets.

The project combines monitoring, data analysis, sonification, and the development of installations.

Outputs include technical reports, sound archives, multichannel installations, physico-acoustic models, and educational materials. It involves glaciologists, museums, research institutes, artists, and schools. Applications span research, art, environmental education, and data-driven public communication, with the aim of establishing a replicable standard for acoustic observation of Alpine glaciers.
