Abstract
The delay time of evoked otoacoustic emissions (e-OAE) is not twice as long as the travelling time along the basilar membrane as expected by reflections. But the long delay of e-OAE can be explained by assuming Bragg's reflections in the one-dimentional model of the basilar membrane.
The computer simulation provided a reasonable explanation for the following features of e-OAE:
(1) the relation between the width of the exciting tone burst and the delay time of e-OAE;
(2) the frequency dependent delay time (about inversely proportional to frequency); (3) the input-output level dependence; (4) the multiple echo.
