Hearing the past

Visitors to Stonehenge in Wiltshire rarely experience the historic site without the rumble of traffic noise from the nearby A303. But UK researchers have managed to recreate the sound of a ritual there, as heard by our ancestors 4,000 years ago.

The research - which starts in an echo-free recording chamber and uses latest computer modelling techniques - has also been used to recreate the acoustics of Coventry Cathedral before it was destroyed in World War II.

The same work is also being used to design better buildings of the future - with the acoustics of Stonehenge for instance, helping to inspire modern concert venues. It is also influencing the way museums use sound to give visitors a sense of history, such as the hustle and bustle of railway stations during the age of steam.

For BBC Radio 4, Prof Jim Al-Khalili went to investigate the sounds of the past.
