  • Abstract
    It is known that bats use echolocation to detect their prey. Their sonar system allows echolocating bats to navigate with high skill through a complex, three dimensional environment at high speed and low light. The auditory analysis of the echoes of their ultrasonic sounds requires a detailed comparison of the emission and echoes. In order to use the best shape of a transducer, in this paper it was used the spatial impulse response and it has been studied the directivity pattern of a concave transducer with different dimensions.
