Abstract
The general context of this study is to perform cross-validation of analytical and numerical calculations of vibroacoustic response of panels under a turbulent boundary layer excitation. This article focuses on the specific case of a rectangular aluminum panel with controlled simply-supported boundary conditions, and tested in a lowspeed anechoic wind tunnel (Mach number ≤ 0.12). An underlying goal is to setup a microphone array for directly estimating the radiated sound power from the panel. The vibration of and radiated sound power from the panel are first estimated under a shaker mechanical excitation so as to verify agreement with theoretical calculations and the relevance of the proposed shoebox-shaped microphone array. Similar measurements are then conducted under a turbulent boundary layer excitation. Finally, estimated radiation efficiencies under point mechanical and turbulent excitations are compared. © 2019 Institute of Noise Control Engineering

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
