the Echolocation signals, the sound signals emitted by animals with orientation in space by echolocation. Do bats distinguish snap sonar signals emitted by the language (some bats), and the voice emitted by the vocal cords (all bats). Sonar signals can partially or completely be located in the audible frequency range (e.g., skladchatogo hirokoji) or ultrasonic (most bats). Sonar signals can also be abruptly frequency-modulated (with a significant drop in the frequency in time, like most bats), hollow frequency-modulated (with a slight drop in the frequency in time, for example skladchatogo shirakawago) and constant frequency (for example, a Tulip-like horseshoe bats). Echolocation signals in different species of bats are different in structure, duration, power and frequency range and, therefore, are important to define in nature. Acoustic features of the echolocation signals of bats studied using ultrasonic detectors.
