Abstract : Experiments with an analog ear equipped with a representation for cochlear nonlinearities reveal responses to simulated and real echoes which suggest how echoranging animals might operate. An explanation is offered for target ranging and identification, and for the several phases of pursuit activity demonstrated by the insect catching bat. The echoranging phenomenon has been 'humanized' in order to employ psychoacoustics as an aid to understanding. Concepts are extended to other animals than the bat, including man. (Author)
