Sound insulation standards in the uk: A decade of change
Bibliographic record
Abstract
The article outlines the causes and consequences of change in residential sound insulation standards across the UK. It was also put forward in the draft document, and later confirmed in the full ADE, that 10% of attached dwellings of any partition type on a site should be subject to Precompletion Testing (PCT) for sound insulation. The RSD project commenced in September 2002 and was to be completed 9 months later for submission by the house building industry to the government The scale of the design and test element to the project was a world first. As each new wall and floor design would require at least 30 tests, spread over 4 different construction sites, using at least 2 different developers and 3 different testing companies. The process of gaining RD status remains the same today, with over 30 RD wall designs and over 20 RD floor designs incorporating masonry block work, concrete, timber frame and steel designs.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
