Explore the collectionsStart with a subject that interests you. Each collection brings its own questions, methods and source records.
Vinyl playback
Measurements of vinyl playback systems, connecting test-signal analysis with the setup and conditions behind each result.
Environmental sound
Sound-level observations from real environments, bringing measured acoustic levels together with the context needed to understand them.
Our approach
A useful study explains what was investigated, how it was tested and what the evidence supports. Measured results, calculated estimates and interpretation are kept distinct.
Results describe documented conditions, not universal product ratings. Unknown information is identified rather than filled in with assumptions.
The subject determines the tools and methods—not the other way round. New topics can join the collection without changing its purpose.
Setup, environment, capture conditions and analysis methods provide the context for interpreting each result.
