FIG. 1.

Probe- and suppressor-stimulus paradigms used to evoke the TEOAE. Each panel includes three stimulus intervals ($s_1$, $s_2$, and $s_{1,2}$). During $s_1$, only the probe is presented through channel 1 of the transducer. During $s_2$, only the suppressor is presented through channel 2 of the transducer. During $s_{1,2}$, the probe and suppressor are simultaneously presented through channels 1 and 2, respectively.
