A major restoration project at a remote Paramara-era Shiva temple in the Dewas district of Madhya Pradesh has led to the discovery of unique copper-clad acoustic vents. These specialized ducts, integrated into the stone walls of the garbhagriha, were designed to amplify and resonate specific frequencies during Vedic chanting.
Conservationists believe this finding highlights the advanced understanding of Sthapatya Veda and architectural acoustics employed by the Paramara builders. The vents were found during the removal of centuries of accumulated debris and lime plaster, revealing original polished copper linings that have remained largely intact for nearly a millennium.
