We first simulated the approach of an echolocating bat flying at a speed of 6.3 m [s.sup.-1] , assuming a call amplitude of 125 dB SPL at a distance of 10 cm (Jensen & Miller 1999, Holderied & von Helversen 2003), and a spreading loss of 6 dB per doubled distance and atmospheric attenuation of 1 dB m-1 (Sivian 1947, Lawrence & Simmons 1982).
