Rats' audible frequencies start at about 200 Hz at the bottom and go up to about 60 Hz from 20 Khz in the ultrasonic range. This application generates frequencies specialising in the ultrasonic region and displays the waveform on the screen. 10 patterns of multiple frequency combinations 1500hz - 35000hz 15500hz - 35500hz 20000hz - 40000hz 20500hz - 40500hz 25000hz - 45000hz 25500hz - 45500hz 30000hz - 60000hz 30500hz - 60500hz 35000hz - 65000hz 35500hz - 65500hz Notes. Depending on the nature of the device speaker, sounds derived from high frequencies may be emitted. Do not listen to high-frequency sounds with your ear directly over the device speaker for long periods of time as this may be harmful to your health.
