For those wondering about if it would be audible and if the technology would impact pets, here's the receiver's patent application:

The frequency range they list in examples for applications are from 40kHz to 110kHz. This actually does overlap with the hearing ranges of dogs and cats somewhat. Wiki lists the dog hearing range from 40Hz to 60kHz and the cat range from 55Hz to 79kHz.
Humans should be safe though since a common number for the high-end of human hearing is 20kHz.
- desdiv 12y ago>Humans should be safe though since a common number for the high-end of human hearing is 20kHz. That doesn't mean it's safe for humans, it just means it's inaudible to humans. In many circumstances, an imperceivable threat is far more dangerous than a perceivable one. Laser is one example. If a visible laser beam hits your eyes, your blink reflex will kick in and (hopefully) save you in time. But a laser beam outside the human visual spectrum will literally burn your retina out before you figure out what's going on.
