I fully intend to break these devices if I ever hear them. I'm over the age of 30, and can hear them quite clearly; it violates my right to be in public spaces.

I fully intend to break these devices if I ever hear them. I'm over the age of 30, and can hear them quite clearly; it violates my right to be in public spaces. Even if the device is installed in privately owned property, it's not like the sound waves magically stop at the end of that property. Regardless of the law, the use of these devices within hearing of public space is against the public good, and they should be destroyed if heard.
