I can't even root this phone anymore or flash anything on it since I accidentally let it autoupdate to a more recent version of Android and can't figure out a way to revert.I see that you've taken the Android out of the equation, but if you do need to return to it in the future you could always see if there's a custom rom available for the phone model you're using. I highly doubt anyone is going to worry about EU regulations about sound and leave that in the code.
The people who have legitimate reason to be on site are not typically going to be loitering within the range of the broadcast any longer than a few minutes' smoke break, so even if they hate the music selection (very few complaints so far) it's not a torturous ordeal. Only time someone was adversely affected was one fire alarm service contractor who had to spend a few hours installing a transceiver underneath one of the broadcast units while it was doing a long stretch of Bundeswehr marching music.r/thathappened
But if it really did, great work!
P.S. Why would anybody else in the area tolerate the noise, if it's so offensive to the hoodlums?
The undesirables and passerbys are not so tolerant, they need rap and hiphop music like we need air and water to live, and a lot of non-nig music is like ear torture to them if they have to endure more than a minute of it. The only way they can reliably beat the system now is by blasting their own music through their earbuds at hearing-damage volume levels. And whenever I suspect they are trying to get clever by doing things like that, I increase the pressure by switching to a single-track playlist that will repeat the same short song ad nauseum.
