History and variations of Lindsay's wheel of acoustics: From a nested pie chart including words to a drawn acoustics world
Bibliographic record
Abstract
In 1964, Robert Bruce Lindsay introduced “The Science of Acoustics,” a graphical representation that has become popular and is often called the Wheel of Acoustics. This communication first recalls the historical context and initial versions of this representation. Adaptations to its original design are then introduced. Some follow the idea of a wheel representation but focus on specific acoustic domains or perceptual descriptions of sound. Other adaptations propose a slightly modified arrangement of the wheel's elements while including icons to illustrate covered topics. We introduce a wheel that blends realistic and iconic representations following a primarily hand-drawn and artistic vision. This visual tool can be used for acoustics teaching and popularization to improve audience engagement and provide more in-depth and concrete examples. The Drawn Acoustics World is provided in English and French versions, and also in a text-free version that can be used to adapt to any language.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
