The final lecture becomes a listening room. Each instrument offers a short
guided encounter, source data, a non-audio representation and a complete
mapping disclosure. Visitors respond to one scientific question rather than
rating musical taste.
Public dataset → documented cleaning → inspectable mapping → accessible
interface → listening task → evidence from visitors → revision note. The
instrument succeeds when its claim and its limitations stand without the
designer beside it.
We close by asking what sonification adds to scientific inquiry and where a
graph, table or spoken description remains the more honest tool.

Use this page before the slides, then return to the checkpoint after the lab.
After this week, you can
Frame one precise astronomical question for a first-time visitor.
Publish source, mapping, uncertainty and alternatives beside the interaction.
Use observed visitor behaviour to justify one final revision.

Five first-time visitors attempt the same pattern-location task. Values are a teaching model, not an astronomical observation.
Worked notebook
A visitor test with a decision
Five first-time visitors attempt the same pattern-location task.
Let visitors begin without a verbal explanation from the designer.
Record task result, control failure and interpretation separately.
Group failures by interface, mapping or misunderstood scientific claim.
Revise the largest repeated failure and rerun the same task.
What the method supportsPreference comments may guide polish, but repeated task failures identify the consequential revision. The final note connects that change to observed evidence.
CheckpointThree visitors like the sound, but two of five answer the scientific question correctly. What should the release note prioritise?Reveal the reasoning
The failed scientific task and the revision made in response.
The instrument exists to support an investigation, not only a musical experience. Enjoyment is useful audience evidence, but it cannot substitute for whether the stated pattern became understandable.
