You said in your previous post that you couldn't get arrested for making noise! That was what I was addressing!
First off I'm not sure you can get arrested for making noise. Maybe you can. I have no idea. Just a fine? I dunno.
Secondly, I never said you couldn't get arrested for making noise.
You said there were noise ordinance laws and I said "not all noise" ("Yes but "public places" aren't pin drop quiet." was the exact quote)
No one has yet shown me these things reach the level of that area's noise laws.
You said "I can go out and read the Bible in a loud squeaky voice and I doubt I will get arrested." and I said "Actually, if it's loud enough, you can.", let's leave it at that.
I think it's bad to do that to anybody, I just wanted to hear your opinion. I'm surprised anyhow. I thought people that agreed with the use of such device would abhor using it on anyone else.
If it's a legal noise, it's a legal noise.
This is not a "young people suck" argument. If it were old people complaining and it was legal, tell em to go play bingo.
Fine to hear that. (pun not so much intended)
Yeah, that's what I'm curious about. If this happened anywhere near here, the public outcry would be immense. Then again, I think people from the Netherlands would say the same thing a few months ago. 
Just thought of something. It said permanent. If they turn it on and off for business hours, is it permanent?
To me permanent would be "all the time", and if it's not on "all the time"... maybe that law doesn't apply.
Perhaps, but I would think it being on and off every business day would qualify for being permanent. We'd need a lawyer to go further into the issue.
Just to drive the point home, my reason to complain is not public assembly or freedom of association, but the inherent noise and disturbance it causes at anyone who hears it. Those who replied above who heard it seem impressed.
There is nothing wrong with the argument. There are just two issues.
1. There needs to be proof an ordinance exists in that area.
2. There needs to be proof these stores violate it.
And unfortunately, because there are groups against these things, I think they would have checked noise ordinances first. I'm not saying there aren't but the article seemed very "uh.... we're not sure what to do"
I agree, but it puzzles me really. The device's intent seems to be so easy to prove that one has to wonder how is it legal to operate it continuously in public places.
Regardless of that, after a bit of digging I found:
A reference to how loud it is and
a few references about noise levels.
The first link indicates that the noise the device creates has a volume of 85 dB.
The second link indicates this is slightly below the noise level of a lawnmower. It also says 8 hours of 90dB can cause damage.
To me it seems these devices operate at the very edge of safety.
