Outputs of the two loudspeakers used during LDV sweep recordings from Coupled membranes: A mechanism of frequency filtering and transmission in the field cricket ear evidenced by micro-computed tomography, laser Doppler vibrometry, and finite element analysis

Figure S3. Loudspeaker outputs. (a) Speaker 1, cone-diaphragm VISATON FR58, corresponding to acoustic condition 2 and figure 3b-f in the article. Outputs obtained during figure3c experiments (n=20), mean ± SEM. (b) Loudspeaker 2, ribbon-diaphragm Heil air motion transformer (ESS), acoustic condition 3 and figure 3g,h. Obtained during figure3g (orange) closed spiracles experiments (n=10), mean ± SEM. [Latham B, Reid A, Jackson-Camargo JC, Williams JA, Windmill JFC.
