TEOAE Response Simulator

Adjust the parameters for each ear and watch the trace and the signal-to-noise verdict respond. A low amplitude or a high noise floor pushes the SNR below the pass criterion. Every figure is hand-rolled SVG driven by a pure-math signal model — no recorded patient data.

Simulated TEOAE traces. The emission is modelled as a latency-dispersed cochlear echo — higher frequencies return earlier. Drag the R and Lmarkers on the trace — or use the sliders — to set each ear's peak latency and amplitude, and watch the signal-to-noise ratio drive the pass / refer verdict. Educational model only.
