Sound around you is a project by the University of Salford (UK). The goal of the project is to create a sound map of the UK as part of a new study into how sounds in our everyday environment make us feel.
To participate in the project you can record a sound clip with your mobile phone or portable recorder and send it to sound around you website, together with the answer to some questions about the recorded sounds.
An interesting attempt. I wonder if a person living in a busy and noisy city center feels as relaxed as a person living on the countryside. After analysis by 'acoustic scientists' significant findings will be reported on the website.
