What I find ironic, is the police are doing a copyright infringement (unauthorized public performance of these songs) in order to infringe on citizens' rights. Why are record companies not more pissed about this?

Because they don't lose money over it the way they do over other types of unauthorized public performances.

Does it suggest that system of IP is genuinely designed and deployed to protect art? Or capricious exercise of state power?

Police wont't generally use something like this as it would interfere with bodycam which includes a microphone.

The cops are not trying to post their footage to the socials. They want you to not be able to do it. If they need their footage, it's to prove you were being an asshat and deserved whatever happened to you. If you need their footage, it'll mysteriously not be available for some technical or clerical error.

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/ Definitely thought provoking research :)

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.

It's harmful to constantly hear sound, I wonder if it's our perception that makes it harmful even if we don't realize that we hear something? Is it harmful to hear sound threats outside of our range? Is it harmful to constantly use active noise cancelling?

> It's harmful to constantly hear sound

Are we saying our brain is not processing sound while we sleep? Ain't we hearing sound 24/7?

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.

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.

It's illegal for movie theaters to jam cell phones. If this actually works and becomes popular, I don't imagine it would take too long before this became illegal too.

It is Illegal to jam the phone signal in case of emergencies AFAIK. Not aware of it being illegal to jam recording devices in such an environment in which they do outline (somewhere) no recording allowed in the theatre.

Audio is an odd thing in law - in the UK I can record many things audio more than you would legaly be allowed to video.

But privacy laws are the ones that curtail video recordings mostly and with that - this kinda sits on the other side of the fence.

However - public nuisance may prove an area and pets may well dislike this, so if anything it may be classed as an assault upon an animal. Depending upon the impact upon animals like dogs.

So my main concern would be public area's with people using guide dogs - will this cause the dog distress and what would be the impact.

So I'd imagine already laws that may see this fall foul of - but like many things it will be how it is used and not ownership.

Interesting to note that someone opened an issue in the linked GitHub repo mentioning that the system doesn't work with iPhone 8 and above: https://github.com/y-x-c/wearable-microphone-jamming/issues/... edit: Looks like (from the reply) it's the waterproofing membrane over mic that's rendering the jammer useless.

That may well be fixable, case of what is the resonant frequency of the water protection an tuning this to induce resonance to overload the sensor - may well work. Though inducing resonance in the glass screen may well achieve the results.

I'd also be interested in testing this with contact mics as from my experiences - this may not work upon those at all.
