Abstract
Acoustic resonance is a phenomenon which is known to \nhave severe repercussions in a variety of industrial systems. \nAcoustic resonance can cause high levels of vibrations leading \nto damage or premature failure of critical components. Although \nacoustic resonance affects a broad spectrum of industrial \nequipment, piping systems will be of focus in this work. Both \npassive and active damping techniques were previously \ninvestigated. However, there is a need to investigate the \npracticality of such devices when implemented in industrial \nsystems. Herschel-Quincke (HQ) tubes have been selected for \nexperimental study throughout this work. The experimental \nsetup consists of an open-air loop pipeline system which is \ncapable of exciting a standing wave with a fundamental \nfrequency of 30 Hz and a target dominant fifth mode of 150 Hz. \nTransmission loss measurements were performed by means of \nthe two source-location method. Insertion loss measurements \nwere performed with a straight pipe used as the baseline. The \ncurrent work has shown that Herschel-Quincke devices have \npotential for practical implementation into resonant piping \nsystems in industry.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
