The constant term (rms and peak SPL) of the logarithmic function describing the intensity compensation between 0 and 0.70 m from the target as three target types are approached by the bat

SPL, sound pressure level; rms, root mean square.
Note that the absolute pressure emitted by the bat depends very little(maximum difference 4 dB), if at all, on the target that was intercepted.
