Yet a new study suggests many MPs in the audience wouldn’t have been able to hear him properly.
Catriona Cooper, a digital archaeologist at the University of York, used a computer model to recreate the acoustics of the 18th-century Commons, which was housed in the former St Stephen’s Chapel. Then, using reports of how many people were in the building at the time and where they would have sat or stood, she worked out how Wilberforce’s speech on May 12th 1789 would have sounded to those present.

In fact, the best places to listen to this and other Georgian debates in the Commons were largely out of sight, in the doorway or behind the Speaker’s chair.
