Walking as a research method is an interesting concept but not one I had considered before. How many times per day would you say you pay attention to the sounds and noises around you? Once? Twice?
Interesting though to realise how exploring places with sound walking can show you how much you miss out when you’re not paying attention. On the other hand it can be difficult in a bustling city to hear the voice of an opera singer or the birds chirping in the trees nearby.
