Simple & Versatile Bat Detection. Listen to bats in real-time! Take a closer look at echolocation bats using the included BatScan Analysis software! Fast and easy analysis of bat sonarBatScan processes PCM format digital audio data such as .wav sound files. Default settings have been optimized for use with the Baton.BatScan will operate with 8-bit color. However, a 24-bit color is required in order to save screen images as graphics files ( jpeg or bitmap ).BatScan will run under Windows 95, Windows 98, Windows ME, Windows NT 4.0, Windows 2000, Windows Vista, Windows XP, Windows 7, 8, and 10. BCM and Myotisoft has used BatScan in Windows on a Mac running Parallels.BatScan runs best with 128MB or more of RAM memory.*MP3 files must be converted to WAV file format before usable by BatScan BatScan Analysis Software The Baton is a simple but versatile “frequency division” bat detector that allows the listener to hear the ultrasound produced by echolocating bats. The Bat Baton has a division factor of 10, meaning the sounds of a 50kHz bat is reduced to only 5kHz—well within the range of human hearing! These calls are captured through the microphone located at the top of the baton, and then emitted through the front-facing speaker. For private listening, the 3.5mm jack allows the use of headphones, as well as provides the option to connect directly to the computer for use with the the included software Calls can also be recorded on other devices such as MP3 or minidisc for later analysis. The Baton is also ideal for listening to Orthoptera (grasshoppers and crickets) whose communication is in the upper part of, or above human hearing. Listening to Echoes When a bat echolocates, it produces an extremely loud, high-frequency pulse of sound. Sound vibrations create “pressure” waves on the air emanating outward from the bat’s mouth. These waves propagate thru the air just like ocean waves propagate thru water. When the sound wave hits an object, it bounces off and returns to the bat, at the same speed, but only a fraction of the intensity. Bats then listen to these echoes, discerning minute differences in their returns to each ear in order to locate an object of interest in 3D space.
