Estimation of the acoustic range of bat echolocation for extended targets (*)

by Wolfram-Peter Stilz and Hans-Ulrich Schnitzler (2012), J. Acoust. Soc. Am. 132 (3), 1765-1775

c1 (reflection loss)
c2 (spreading)
dynamic range [dB]
frequency [Hz]
temperature [C]
humidity [%]
pressure [Pa]
c1 & c2 combinations of analysed targets





(c1 = target strength re 1m) 


octave log: c1=-6.0; c2=-20.0; dr=100; f=20000; t=20.0; h=50.0; p=101325; d=56.2
atmospheric attenuation [dB/m]: 0.52
echolocation range [m] = 56.2
