Example of the latency determination procedure.

<p>Envelopes of a 1 kHz TBOAE from a single subject are shown on a linear scale for stimulus levels from 40 to 80 dB. The white circles connected with solid lines mark the same maxima across different stimulus levels. Black circles (slightly offset for clearer presentation) connected with a dashed line mark the highest response for each stimulus level (the WS latency).
