Aircraft Cabin Active Noise Cancellation Mechanism Using an Actuator Gimbal System
Bibliographic record
Abstract
<p>To reduce the noise pollution inside an aircraft cabin and make the air travel comfortable to passengers, this project develops the required subsystems for a seat side active noise cancellation mechanism which uses a gimbal system and a single tone noise cancellation algorithm. A three degree of freedom gimbal system is designed using three linear actuators to adjust the movement of the speaker. A control program is developed and implemented to control the lengths of the linear actuators based on the required movement of the speaker. For noise control, a program is developed which generates wave signals for the noise source speaker and collects the noise signal from the measurement microphone. A FFT program has also been implemented to identify the frequency of the noise signal which can be used to drive the noise cancellation speakers. Therefore, this project lays the groundwork for the development of an effective and practical aircraft cabin active noise cancellation system.</p>

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.
