Abstract
The presented research deals with the acoustical performance of a proposed grand lecture hall using experi mental and modeling techniques.The primary challenge for the senior undergraduate engineering group was that the room has yet to be fully designed or constructed.The secondary goal was to optimize the design of the room using the computer software ODEON in the early design stage rather than after it has been built as is often the case.Reverberation time, early decay time, clarity and STI were the four acoustical parameters considered.The modeling software was also validated using test measurements conducted in a similar lec ture room.The results of the present room design demonstrated less than ideal reverberation time and early decay times for the proposed room use but above average clarity and STI values.Design suggestions are given to increase the acoustical performance of the proposed lecture hall. r s u m La recherche prsente est une tude des conceptions pour optimiser les proprits acoustiques d 'un amphi thtre par mthodes exprimentales et avec les modles informatiques.Le principal dfi pour le groupe d 'tudiantes de quatrime anne en gnie tait que la salle n 'a pas t encore compltement conue ou con struit.L'objectif secondaire tait l 'optimisation de l'amphithtre en utilisant le logiciel ODEON au stade de la conception, plutt qu'aprs que la salle a t construit, comme c 'est souvent le cas.Les quatre paramtres du son en considration taient: le temps de rverbration, le temps de dcroissance, la clart et le STI.Plu sieurs exprimentes ont t men dans un amphithtre similaire pour corroborer le modle en ODEON.Les rsultats du prsent amphithtre conceptuel ont dmontr des niveaux de temps de rverbration et temps de dcroissance moins que ceux qui seraient idales pour ce type de salle de classe, mais ils ont aussi indiqu des valeurs de la clart et de STI au dessus de la moyenne.Les suggestions sont donnes pour augmenter la performance acoustique des paramtres sous-performants.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
