Abstract
Interference noise seriously affects the recognition accuracy of the target acoustic field. To reconstruct acoustic field of the target sources in non-free acoustic field, a method of acoustic feild separation and reconstruction with 2-layer microphone array is presented. Wtih this method, spherical harmonics in different orders are superposed to describe acoustic pressure distribution for different sound sources, respectively. The coefficient vectors are obtained by matching the measured pressure with the mathematical model. As the coefficient vectors are not changed with the position of measurement planes, once these coefficients are specified, the acoustic pressure of the target sources are determined. The methodology is examined numerically in the acoustic field with two transversely oscillating rigid sphere. The results show that, when two sound sources on the both sides of the measurement arrays, the error of acoustic field separation is 7.36% for the frequency, this method can improve the accuracy of acoustic field recognition.

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
