Abstract
Averaged click-evoked and derived non-linear responses have been measured in normal ears to assess similarities and differences between the results obtained with the two methods. Computation of the input-output curves of click-evoked otoacouslic emissions with a short-time procedure reveals time-varying properties and the presence of saturation phenomena affecting, to various degrees, the linear content of emissions. Present preliminary results provide some guidelines towards the assessment of the relative role of the two techniques in otoaeoustic emission testing.
