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?

So, if you're recording a cop in the next few years, make sure to use a waterproof phone.
Police wont't generally use something like this as it would interfere with bodycam which includes a microphone.
That is exactly why they would use something like this.

I am curious about ANC as well. I used to wear headphones with ANC 8h+ a day and started to hear noise in my ear.

Hmm I'm not so sure about that; do you have any source for that? My intuition says that it's nigh impossible to find completely quiet places in daily life; there's always some noise, though it could be imperceptably quiet.
If constant sound is harmful, I'd imagine we'd all have lost our hearing by now. I reckon any harm woulc come from volume, not just simple presence.

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?

#46Are they not able to just use phase shifts and beamforming on the transducer array instead of the odd keep-moving-your-bracelet design?

In many countries this is unauthorised broadcasting.

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.
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…

I don't see why that would happen. ANC plays an inverted signal to counter noises. It's not just perception that it makes sound quieter. When the original sound wave and counter sound wave collide they physically cancel out.

No one is going to buy this. It doesn't jam your voice at all. It introduces enough distortion and noise so that computer speech recognition software gets 4/5 words wrong. Let me make a comparison. Claim: Those capchas with "type in the word you see" have an error rate of 4/5 letters when read by a computer. Yet here we are, humans, reading them just fine. Now, if you're a conspiracy theory fake elected moon landing…
> Yet here we are, humans, reading them just fine. I've met a lot of captchas that I couldn't reliably solve. I guess that proves I'm a robot.
Same here. My guess is that they constantly AB test/explore captchas to push the envelope of genuine humans users in order to make it as hard as possible for the bots.
