London Sound Survey is a growing collection of creative commons-licensed sound recordings of people, places and events in the capital. Historical references are gathered to find out how London’s sounds have changed. Topics covered are eclectic including auctions, market traders, charity fundraising, fairgrounds and amusements, soapbox orators, calls to worship and beggars and hustlers. Contextual information includes date of recording, the name of the recorder, location, summary of content and technical details of the recording. A sound map enables users to identify the sounds of a particular area of London.
