Fig. 7. (A) Peak wind velocities measured by the anemometer at distances 20–60 cm from the target (N=94). The anemometer was within 18–30 cm of the target in 77% of the trials. The shaded boxes indicate the percentage of measured peak wind velocities that fell between 0–49, 50–99 and >100 cm s^–1 for the data collected with the anemometer within 20–30 cm of the target only. (B) Distribution of peak accelerations for 66 of the trials in A. Peak acceleration was calculated using the onset time of the anemometer detecting the bat-generated wind to the time of the peak velocity. (C) Comparison of peak velocity and peak acceleration for each trial in B. For bat-generated wind, peak velocity and peak acceleration were closely related, with peak acceleration increasing exponentially with increasing peak velocity. The equation for the exponential best fit line is f(x)=4.980398x10^–1*exp(4.814839x10^–2*x).
