This is a wonderful site from the University of Salford in the UK. Listen to soundscapes which have been recorded all over the world. Navigate on the map to find a place of interest, listen to the recording and read the information about the location. Upload your own soundscapes using the site or download the iPhone and iPad app at https://itunes.apple.com/app/i-say/id516927213. It's a useful geography resource and should get your students thinking about the sounds around them.
