Smartphone trial to capture Heathrow flight noise

Residents living under the Heathrow flightpath in west London are being asked to take part in a trial to record the level of aircraft noise using smartphone technology.

The research is being carried out by University College London (UCL).

BBC London's Gareth Furby has talked to Isleworth resident Maggie Thorburn, Joe Ryle and Christian Nold from UCL and John Stewart of Hacan, a campaign group against aircraft noise.
