Cool research. Given that you are also jamming hearing aids and other microphones, don't think it's practical to be used in real life. Off topic: check out Pedro's other work http://plopes.org/ http://plopes.org/ Definitely thought provoking research :)

Depends of what real life scenario is. A cafe, maybe not. A meeting room, likely yes. There at least you can declare that a hearing aid is used. The very point of the device is to jam other microphones. Not going to last very long, though; ultrasound filters will soon appear on all relevant gear, including mobile phones.

  yeah, then the ad tech is just moving onto the next best thing. SDR.

  The microphone's worst enemy is the pencil. ((Just wait until some scrappy thesis describes how to determine character being written by pencil based on the vibrations of sound being made from the friction between a carbon based utensil and a paper pulp based medium such that the intended letters can be derived based on the length, count and direction of the audio signals derived from the sounds of the writing utensil against the medium.

    You know, that sounds like language from a patent application. I actually AM licensed as a patent agent, but I'm not practicing so I can't get you that patent.

      Also that's now prior disclosure and could be cited against the patent application.

  > Not going to last very long, though; ultrasound filters will soon appear on all relevant gear, including mobile phones. Only if this technique actually gains widespread use. Even then, it will most likely only appear on gear that must still record, such as body cams. For consumer tech, this would just be additional costs, which the manufacturers are not going to bother with.

  If that meeting room also has remote attendee's then that may well prove the issue. However with ultrasonic filters - you could cone of using this. Then such approaches have often been used like vibrating windows to curtail laser microphones and yes the trick of taping a vibrator to the window does work - though not in keeping with your boardroom aesthetics unless your Anne Summers or the like.

  I think the parent refers to if a hearing impaired person with hearing aid is present in the meeting room ...

  If I have a relationship that gets me into a conference room with some people, I'm not going to run a fucking microphone jammer there. If I had someone in my conference room do that I would be extremely sketched out.

    It's not about the people they see in the room, it's about the people they don't see in the room.

Cool studies. He sure came a way from his earlier "human component motion platform" (AKA "have your buddies lift and shake you while in VR")

To test the hearing aid, just walk into your local cafeteria at around 2pm (aka dinner rush), and see how many people start reaching for their ears.

Given such brute approach to microphones, I almost expected to see new pipe bomb design there.
