Okay... from TechCrunch: "not Bluetooth".
Also it says it emits from "18 and 22 kHz" which "most people can't hear". Um, most adults. 18-22 kHz is DEFINITELY audible to teenagers and children. Or how about a dog! On the flipside, insects don't like hypersonic frequencies either, maybe I'll get less bites. Anyone remember mosquito ringtones blaring during class where the teacher would not even notice? That's how they get kids to quit loitering. So that might be a benefit for the WFH parent. This is what they use to see babies so imagine what it can see beyond your camera.
I already know from using ultrasonic devices that I can hear this. They're loud and sound weird.
From my understanding, frequencies in that range also interfere with hearing aids, monitors, and smart devices. In my head I'm like oh man, a bigger microphone array is going to make harvesting that audio data so much sweeter, that's a huge value proposition! If those devices are vulnerable to 'dolphin' attacks, or inaudible commands, this is yet another security concern.
I wonder if they'll include support to map the acoustics and layout of your room through sound detection for projection optimization. Scary and enticing. This seems like a reasonably well designed tool that can either make my life more productive or help destroy it simultaneously. I mean if it's covered as an office expense, it's better than opting for webcam, monitor, microphone, speakers in a more svelte package.
Apologies if this comment seems par for the norm to hate on Zoom. I'm actively trying to give them the benefit of the doubt to balance discussion here, but some of these choices are specifically bad.
