sounds!

I just found this app. There are animal sounds, nature sounds, life sounds (complete with flatulence), sports sounds, etc. There is a "traffic" category with sounds that relate to traffic. There is a car engine starting sound, a crash, a car braking, etc. I plan to use this app to expose a few of my blind students to traffic sounds. What does it mean if you are walking in a parking lot and hear an engine start? What is expected of a pedestrian walking when they hear an ambulance? What is expected of a driver of a vehicle? With in climate weather days ahead, I need O&M lesson ideas for inside! I will report on how it goes...
