I have shown my guide dog how to find a few poles for audible pedestrian signals. I don't always use them. This is a button you push and when the light changes, it gives you a signal. Here where I live the north south lights chirp and the east west lights used to cukoo but now play something called the Canadian melody. Maybe I shall try to record them and post the audio here for your listening pleasure. I use them mainly when it is quiet and little traffic and or when traffic is tough to read for some reason. I don't always know which intersections have them and where the poles are. The poles can actually be quite far from where I line up to cross a street. Anyway, yesterday morning, my guide dog pranced up to a pole at a corner. I thought she was sniffing it and was about to say no. But, I put my hand out and she wagged her body so hard, and there was an audible button at a corner where I never knew a signal existed. We were both pretty excited about it I must say. She got kibble. I got a good feeling in my heart! Smile!
