Dogs' hearing extends to 45 KHz. Cats hear up to 79 KHz. How do all these ultrasonic audio systems affect them? Do they cause pain? Do they damage the animals' hearing?
I won't (knowingly) use ultrasonic audio systems until I see some research on this topic.
- isostatic 9y agoPresumably the amplitude is no louder than normal speakers. 120db will be dangerous to humans and dogs. 20db won't. Listening to white noise isn't painful.
- brian-armstrong 9y agoIf you want to try out Quiet's audible profile, you can imagine that ultrasonic is the same volume, but pitch shifted up. Making modems louder doesn't help transmission anyway, so it's pointless to do so. https://quiet.github.io/quiet-js https://quiet.github.io/quiet-js
