Whistle for dogs (ultrasound)

The application is a free and entertaining ultrasonic whistle. It is intended primarily for people who have a dog! With the help of the application you can train your dog, communicate with her - show what is good and what's bad!
The application reproduces high frequency sounds (ultrasound) from 10 kHz to 18 kHz. Sounds of this frequency are not heard by people, but they are well heard and reacted to them by dogs and other animals!
Ultrasound - elastic sound vibrations of high frequency. The human ear perceives elastic waves propagating in the medium with a frequency of approximately 16-20 kHz; Oscillations with a higher frequency are ultrasound (beyond the limits of audibility).
