A healthy term newborn, 36 hours old, is screened on the postnatal ward before discharge. The baby is asleep and the room is quiet. The screener obtains a clear recording from both ears on the first attempt.
Findings
— Normal ear— this case
Simulated TEOAE comparison. Educational signal model — not recorded patient data.
● DP emission▮ Noise floor
A normal DP-gram. The emission sits comfortably above the noise floor at every test frequency — the margin between the two is the signal-to-noise ratio. Simplified teaching model, not calibrated normative data.
Diagnostic question
Both ears show a robust emission well above the noise floor, with high reproducibility. What is the correct screening outcome and next step?
