SLOP3255 · Week 11 · Rhetorical audit

When sonification lies

A persuasive sound can make a weak claim feel certain. Technical accuracy alone does not remove rhetoric.

Every mapping carries associations

Rising pitch

may suggest growth, progress or approach

Regular rhythm

may imply stable sampling or periodic cause

Reverberation

may imply physical scale or distant space

These meanings are culturally and musically available. They are not measured values.

Four quiet ways to mislead

Cleaningambiguity and noisesignal was obvious
Quantisationsmall variationnatural categories exist
Decorationboundary of measured datamusic is evidence

The result may remain beautiful. The claim must remain bounded.

The certainty amplifier

Source

Noisy values with overlapping uncertainty.

Several interpretations remain plausible.

Rendering

Quantised notes, strong cadence and triumphant resolution.

The ending feels more certain than the evidence.

Emotional clarity can exceed evidential clarity.

Run the hostile reading

Before explaining your work, ask a listener:

  1. What do you think was measured?
  2. What changed in the source?
  3. Which sound features seem physically meaningful?
  4. How certain does the conclusion feel?

Compare their inference with your actual pipeline. The mismatch is design evidence.

Separate three layers

Dmeasured data
Mmapping and processing
Ccomposition and decoration

All three may be present. The ethical failure is letting C masquerade as D.

Disclosure makes critique possible; it does not excuse a manipulative mapping.

Revise the strongest implication first

RetestAsk the hostile questions again.

Ethics becomes an observable revision process, not a paragraph at the end.

Find the mismatch

Task

Audit a persuasive astronomy sonification and identify where interface implication exceeds data support.

Revise

  • one cue
  • one disclosure
  • one retest

The first revision targets the largest evidential mismatch, not the easiest cosmetic fix.
