Slum settlements have a strong visual identity. We are used to seeing TV footage of densely packed, ramshackle homes squeezed onto strips of land in inner cities. Dr Tom Rice, a sound anthropologist, takes an alternative perspective and explores what a slum sounds like and how this embodies and reflects the local culture. Tom meets up with Dr Tripta Chandola, an urban researcher, who for 10 years has studied the slums of Govindpuri in India’s capital, Delhi.
