There is no way this is going to be detectable, or annoying, like ultrasound at 19kHz! (near or in the audible range!) This is night and day, and there is no way this is comparable to door openers, cleaners, and the rest. Also, OSHA has a limit of 145dB of ultrasound levels (look it up), and these devices use less than 1/4 of that, according to the articles linked online. Enough with the alarmism.

This is an old technology that has not been use because of this. But of course some people never learn as we can not stop human stupidity and here we go again!
