In the video interview on the page they said that it’s something like 25 dB. So technically it’s audible to humans too, it’s just low enough that no one really cares.

In the product page they mention it's 25dBa, but if that's measured using a reference microphone for the human spectrum it's not going to reflect if the ultrasonic frequencies its running at are audible to say, a dog.

The reason I asked is because this is sick, unless it makes my dog cry.

Likely edible as well
