Dogs hear higher pitch sounds than people. That’s why dog whistles seem to be silent. Dogs hear the high frequency sounds that we can’t. High frequency sounds usual travel further than voices and can be heard further away.

Dog trainers use dog whistles to get a dog’s attention. Hand signals are often combined with dog whistles. Some find that different breeds react to different high frequecies. In general, smaller dogs are most sensitive to higher frequencies compared to larger dogs.

Working Frequencies: 12000 to 44000 Hz

Works with:
– The Iphone v1, 3G and Ipod Touch 2
– The Ipod Touch v1 (with external speakers).

Touch the screen to see a Fibonacci square show up. The first square is drawn for you. When the last square is drawn, you will see the spiral beginning in red color. Touch within each square to see the Fibonacci spiral complete. Once the entire spiral is drawn, you can start over by double tapping any white space outside the blue square (for example, double tap the lower right corner to clear the drawing and start over from the first square). Enjoy!
