Table 3.

The same function constants as in Table 2, but now representing rms and peak SPL received by the bat, corrected for geometric spreading,atmospheric attenuation and target reflection characteristics

SPL, sound pressure level; rms, root mean square.

The differences in emitted intensity between the different targets displayed in Table 2 were taken into account.

Throughout prey capture, the echoes from the small sphere are 17-18 dB weaker than the echoes from the big sphere and mealworm.
