Theoretical and experimental work on echo-delay acuity in bat sonar reveals a unique, previously unknown ffeature of the bat's internal representation of sonar targets. Echolocating bats determine target distance, or range, from the delay of echoes. Using the auditory system as a sonar receiver, big brown bats are able to achieve this potential. To understand how the wide frequency span of echoes contributes to the bat's delay images, the frequency content of echoes by removing progressively greater portions of te low-frequency or the high-frequency end of the broadcast spectrum is restricted.
