Deafening buzzer across from Pilsen shelter is targeted to annoy migrants, advocates say – Chicago Sun-Times

The device resembles and sounds like a Mosquito alarm, which is sold as a tool “to reduce anti-social behavior such as loitering, vandalism, graffiti and violence,” according to its website. The devices can get as loud as 108 decibels, or similar to the noise at a rock concert. “Folks do spend a lot of time outside the shelter, so I imagine they can hear it, and kids especially,” one volunteer said. “It can’t be good for your ears to constantly hear that.”
