ANALOG SIMULATION STUDIES IN ECHORANGING

Abstract

An electronic analog of a bat cochlea (18 sections) and electronic circuits for generation of bat-like ultrasonic pulses is described. Ways in which such a system, bat or analog, could extract information about the range and nature of reflecting targets are discussed. Human experiments in which the nonlinearity mechanism of the bat cochlea could be bypassed to provide human listeners with signals similar to those which the bat's higher nervous system must analyze are suggested. It suggests jamming experiments to be tried on bats, which if successful would support the theory of the bats analysis technique.
