Fig. 8. Comparison between moth and microphone membrane tension. (A) Normalised maximum positive deflection (displacement) of the N. pronuba tympanic membrane (TM) and the B&K 4138 microphone membrane at 70 kHz. Each displacement is shown with its corresponding `fit', a Lorentzian for the moth and a sinusoid for the microphone. (B) Tension across a B&K microphone, fitted to a sinusoidal model, and across the N. pronuba TM, and fitted to a Lorentzian, when both are driven at 70 kHz.
