- eyegor 7y agoNah, it's physically jamming the spectrum. Unless someone can come up with a microphone that only resonates in the audible range, this technique will always work. It's akin to pointing a really bright light at a camera.
- unnouinceput 7y agoWhile really white bright will jam your eyes too, an ultrasound will not jam your ear, hence this is actually easier to overcome. Just use dumb microphone, that will cut frequencies over 10Kz and have the unintended secondary effect that Alexa will be even cheaper.
