Summary of several SFOAE properties across geckos as shown in Figures 1, 2 and 3

	Level (dB SPL)	Cutoff (kHz)	τOAE (≥1.5 kHz; ms)
Gekko	−5–0	5.2	2.2–3.2
Hemidactylus	−10 to −5	7.2	0.9–2
Eublepharis (adult)	−5–0	4.3	1.7–2.2
Eublepharis (juvenile)	−5–0	5	1.5–2.4
Coleonyx	−10–0	6.3	1–1.8

The level column indicates the approximate range of the average magnitudes (see Fig. 1 caption) over the frequency range ~1–4 kHz, where emissions were most prominent in all species. Cutoff indicates the approximate frequency at which emission magnitudes started to become indistinguishable from the noise floor, as inferred from the loess trends given the 10 dB criterion (see “Methods”). The final column gives the approximate range of time delays (τ_OAE) for frequencies above 1.5 kHz. These delays can also be inferred from Figure 4 by dividing N_SFOAE trend by the emission frequency (Eq. 1). Stimulus parameters used: L_p = 20 dB SPL, L_s = 35 dB SPL, and f_s = f_p + 40 Hz
