Acoustic perceptions of vessel fitness in southern Africa
Bibliographic record
Abstract
The acoustic properties of objects found in archaeological contexts have seen little attention because they are seldom found intact. Nevertheless, sound is quality of objects that is of tremendous significance during both their manufacture and use. In this article, the authors examine how the acoustic properties of ceramic vessels influence the perception of their fitness for use. Grounded in how sound cues correlate to visual, tactile and olfactory measures of vessel fitness in an ethnographic context, they focus on detecting perceptible sonic differences between damaged and undamaged vessels produced by Zulu and Swazi potters in southern Africa. The article demonstrates how sound is a key quality of vessel ‘strength’ that both potters and clientele use to gauge functional and social suitability. We show that studies of fabric characteristics, such as fissures and voids, in addition to fabric composition provide a means to infer the acoustic properties of archaeological pottery and evaluate the significance of sound in past valuations of vessel fitness. Archaeological discussions of materiality can explore how social valuations of vessel fitness are accessible through studies of the functional properties of ceramics that consider human sensory experience.

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.
