...Dr Rupert Till, an expert in acoustics and music technology at Huddersfield University who believes the standing stones of Stonehenge had the ideal acoustics to amplify a "repetitive trance rhythm" not dissimilar to some kinds of modern trance music.

The original Stonehenge probably had a "very pleasant, almost concert-like acoustic" that our ancestors slowly perfected over many generations

Because Stonehenge itself is partially collapsed, Dr Till used a computer model to conduct experiments in sound.
