Acoustic and geophysical measurement of infrasound from wind farm turbines
Bibliographic record
Abstract
An experiment was conducted to measure and characterize infrasound (and higher frequency acoustic energy) from turbines at a wind farm in Southern Alberta.Simultaneous telemetry and point measurements were acquired from three sensor types: low frequency geophones, acoustic microphones, and a precision sound analyzer.Measurements were recorded for three wind states: low, medium, and high.Down wind telemetry measurements were recorded for thirty (30) continuous 50m offsets, up to a distance of1450 m from the wind farm.Point measurements, coincident with the telemetry measurements, were acquired with a low frequency precision sound analyzer for two offsets: 50m and 1000m from the turbines.The same measurements were recorded with the turbines on, and with the turbines off.The low frequency results of the experiment are presented in this paper. r s u m Une exprience a t mene pour mesurer et caractriser les infrasons (et une forme d 'nergie acoustique hautes frquences) provenant des oliennes d 'un parc dans le sud l'Alberta.La tlmtrie simultane et le mesurage par points ont t faits avec trois types de capteurs : gophones basse frquence, microphones acoustiques et un analyseur de son haute prcision.Des mesures ont t enregistres pour trois tats de vents : bas, moyen et lev.Des mesures tlmtriques ont t prises dans le sens du vent pour trente (30) dplacements continus de 50 m jusqu' une distance de 1450 m du parc d 'oliennes.Des mesures par points, concidents avec les mesures tlmtriques, ont t prises avec analyseur de son de prcision de basses frquences pour deux dplacements : 50m et 100m des oliennes.Les mmes mesures ont tUne exprience a t mene pour mesurer et caractriser les infrasons (et une forme d 'nergie acoustique hautes frquences) provenant des oliennes d 'un parc dans le sud l 'Alberta.La tlmtrie simultane et le mesurage par points ont t faits avec trois types de capteurs : gophones basse frquence, microphones acoustiques et un analyseur de son haute prcision.Des mesures ont t enregistres pour trois tats de vents : bas, moyen et lev.Des mesures tlmtriques ont t prises dans le sens du vent pour trente (30) dplacements continus de 50 m jusqu' une distance de 1450 m du parc d 'oliennes.Des mesures par points, concidents avec les mesures tlmtriques, ont t prises avec analyseur de son de prcision de basses frquences pour deux dplacements : 50m et 100m des oliennes.Les mmes mesures ont t .

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.
