Evaluation of a Probe-Tube Insertion Technique for Measuring the Real-Ear-to-Coupler Difference (RECD) in Young Infants
Bibliographic record
Abstract
A common strategy for measuring the real-ear response of the real-ear-to-coupler difference (RECD) in the pediatric population is to insert a probe-tube separately from the eartip. This strategy is at times difficult to implement while attempting to obtain the measurement from a young infant. An RECD probe-tube insertion technique that involves connecting the probe-tube to an eartip with plastic film for simultaneous insertion was examined on 30 infants. Repeated measurements were completed on each infant to obtain within-session test-retest reliability data. Probe-tube insertion depth was also examined across participants to provide a guideline for the infant population. Findings indicate that reliable RECD values can be obtained in infants when the probe-tube is extended approximately two to four millimeters (mm) beyond the eartip or 11 mm from the entrance to the ear canal. Clinical implications of this work are discussed. Una estrategia común para medir en la población pediátrica las respuestas de oído real a partir de la diferencia oído real-acoplador es la inserción de un tubo de prueba separado de la oliva de insersión. Esta estrategia es a veces difícil de implementar cuando se intenta lograr la medición en un niño pequeño. Se examinó una técnica de inserción del tubo de prueba para RECD en 30 infantes. Se completaron mediciones repetidas en cada infante para obtener datos de confiabilidad en un test-retest dentro de la misma sesión. La profundidad de inserción del tubo de prueba también se examinó en todos los participantes, para aportar una guía para la población infantil. Los hallazgos indican que se pueden obtener valores de RECD confiables en infantes, cuando el tubo de prueba se extiende aproximadamente dos a cuatro milímetros (mm) más allá de la oliva, o a11 mm de la entrada del conducto auditivo. Se discuten las implicaciones clínicas de este trabajo.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
