Sound Mapping Study reveals how far the sound of Bow Bells rang out in 1851 compared to 2012

To mark the publication of the Times Atlas of London, 24 acoustics have created a map to show current zones of earshot for the 'Bow Bells'. They used precision sound level measurements taken whilst the bells were tolling and calculations according to the effects of the UK’s prevailing South Westerly wind. It is the wind direction which causes the sound of the bells to travel eastwards. Most Cockneys living in the City of London close to St Mary-le-Bow Church moved east in the 19th century, but they took their devotion to the church and its bells with them.
