... say researchers who created 3D printed scale model of the ancient monument and found it would have amplified voices and music

• When Stonehenge was intact, the acoustics were more like a movie theater 
• Researchers created a 3D-printed scale model and broadcast 'chirps' at  different frequencies
• The sound lingered, suggesting the unique sound effect was used while speaking or singing 

 

Sound reverberated inside Stonehenge thousands of years ago, according to a new study.

Researchers in the UK used a scale model to study the acoustic qualities of the mysterious monument built some 4,000 years ago, when all 157 stones were intact.

To approximate the original location and shape of the stones, laser-scanned data of Stonehenge's modern-day configuration was combined with archaeological evidence of its original layout - and the team found it was more like a movie theater than an open-air space.

It's unlikely Neolithic Britons had that in mind when they constructed Stonehenge in the 3rd millennium BC, but researchers believe they would have exploited the sound effects while singing or speaking.
