DPOAE measurements in different mouse strains. DPOAEs were measured in Control (A), Vglut3 −/− (B) and Neurog1 KI (D) but not in Atoh1 CKO (C) mice. DPOAE waveforms induced by the same stimuli (f1 = 5.9 kHz and f2 = 7.2 kHz, both at about 60 dB SPL) from the 4 different animals were used as examples. The stimuli (f1 and f2 as well as the cubic (2f1 -f2) and quadratic (f2 -f1) distortion products were marked in (A) and can be extended to other panels. Note that no peak of DPOAE was measured in Atoh1 CKO mice (C). The cubic distortion product (2f1-f2) (E) and its ratio to f2 (F) were also plotted against cubic f2. The noise level was at about 0 dB for E.
