An evoked otoacoustic emission (OAE) measurement technique is proposed to better control for probe distortion. Each double-evoking (2E) stimulus sequence includes three, equal-duration subsequences defined as follows:s1(t)is a single chirp or click,s2(t)=εs1(t−τ)is a copy ofs1with relative amplitude ε and delay τ, ands12(t)=s1(t)+s2(t)is the superposition of the first two stimuli. The pressure response to each subsequence isp1,p2,andp12,respectively. The double chirp-evoked distortion product (2ChDP) and double click-evoked otoacoustic emission (2CEOAE) are defined bypD=p12−(p1+p2).The 2ChDP response may be time compressed to analyze as an equivalent 2CEOAE response. The 2E response family provides a complementary representation between DP measurements and double click-evoked OAE measurements. A technique based on nonlinear coherence quantifies random noise in terms of a nonlinear signal-to-noise ratio.
