I am building a sound map of the world as part of a study into how sounds in our everyday environment make us feel. We need your help! We’re asking people across the world to use our new iOS app on their iPhones or iPads (or any recorder) to record short clips from different sound environments, or "soundscapes"--anything from the inside of a family car to a busy shopping centre. Then we ask volunteers to comment on their soundscapes and upload them to our virtual soundscape map. Recordings and responses will be analyzed by acoustic scientists, and significant findings will be reported on this website. Sound Around You aims to raise awareness of how our soundscape influences us, and could have far reaching implications for professions and social groups ranging from urban planners to house buyers.
