Sonora is two things. For you, it is a soundscape app. For me, it is a live instrument: tens of thousands of people assembling their own sleep soundscapes at home, every night, for real reasons. I study what that behaviour shows about how people respond to sound — and I publish what I find, including the parts that complicate the marketing.
This page collects the research. Everything here states its evidence level, its limitations, and where the data came from.
There is no universally optimal sleep soundscape.
Between-user variation in acoustic response was 7–9× the population-mean effect.
To be presented at Forum Acusticum / Euronoise 2026 in Graz (September). The full study page and open-access paper appear here once the proceedings are out.
The equipment, the recording practice, and how listening data is collected and anonymised.
Sonora is built and researched by one person — an acoustic scientist in Solothurn, Switzerland.
