It's awful in that using the auditory domain is too much an intrusion into the human space. There is enough noise pollution. Interference patterns around the room may generate harmonics at audible frequencies. Young kids can hear high frequencies we forgot we ever could. I can still hear CRT flybacks. Sometimes I thought I heard something electronic in conference rooms but convinced myself it was nothing.
Someone else was complaining about it affecting their cochlear implant. That is horrifying.
It is not so farfetched that it has an adverse affect on health either. America is losing diplomats left and right to some mysterious ultrasonic weapon, or at least that is one of the leading theories.
It is awful that my CPU has to be constantly running a FFT to read this signal. I think Apple has an ASIC which does the Siri voice recognition.
It's awful that it triggers the orange light to be constantly on so you end up ignoring it. What if Zoom is simultaneously using the microphone stream for nefarious purposes.
This is what Bluetooth was made for. This is a worse idea than Wifi over lighting. Even the 9-digit Zoom dial codes are better.
