Abstract
The purpose of this study was to perform computer-assisted noise mapping of an educational environment.The computer simulations were performed using SoundPLAN software.An analysis of the acoustic maps generated by the simulations indicates that contributions to the noise levels found on the campus originate mostly from three streets on campus, as well as from the roads surrounding the outer perimeter -the Green Line and the BR-277 highway.The computergenerated acoustic maps show that the noise levels within the campus exceed the limit of Leq = 50 dB(A) established for educational areas, according to the Brazilian standard for noise assessment in communities.Therefore, the noise maps indicate a critical situation of noise pollution on campus.However, despite this negative and concerning situation of noise pollution, the acoustic maps also reveal several "islands of acoustic tranquility" on campus.These "islands" can be observed adjacent to buildings where sound levels range from 45 to 48 dB(A) and from 48 to 51 dB(A), which are indicated in green tones on the acoustic maps. SOMMAIRELe but de cette étude était de réaliser la cartographie du bruit assistée par ordinateur d'un environnement éducatif.Les simulations informatiques ont été effectuées en utilisant le logiciel SoundPLAN.Une analyse des cartes acoustiques générées par les simulations indiquent que les contributions aux niveaux de bruit mesurés sur le campus proviennent principalement des trois rues sur le campus, ainsi que des routes entourant son périmètre extérieur -la Ligne verte et le BR-277 autoroute.Les cartes générées par ordinateur montrent que les niveaux de bruit à l'intérieur du périmètre du campus de dépassent la limite de Leq = 50 dB (A) établie pour les zones d'éducation, selon à la norme brésilienne de bruit environnemental.Par conséquent, les cartes de bruit indiquent une situation critique de pollution sonore sur le campus.Cependant, malgré ces nuisances sonores, les cartes acoustiques révèlent également plusieurs «îlots de tranquillité acoustique» sur le campus.Ces «îlots» peut être observé près des bâtiments où les niveaux sonores s'établissent entre 45 à 48 dB (A) et entre 48 à 51 dB (A) et qui sont indiqués dans les tons verts sur les cartes acoustiques.

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.
