Finnish researchers have discovered that the smooth rock surfaces of these prehistoric art sites, dating from 5000 -1500 BCE , possess unique acoustic properties that create distinct echoes, transforming ordinary sounds into something remarkable.
They used custom-designed recording equipment deployed from rafts or lake ice to measure the sound reflections.
The findings suggest these sites weren’t merely chosen for their visual appeal.
