These signals are supposed to only be for visually impaired people but it doesn't indicate that anywhere. Pressing the button has no effect on the pedestrian crossing. All it does is makes a noise that lasts nearly 2 minutes. This noise can happen any time, 24 hours a day, 7 days a week. There are 2 signals on each corner, that means there are a total of 8 signals near us. So potentially any one of these can disrupt our lives at any moment. We can clearly hear this signal with the windows closed and the blinds down.
