The sound is carried by waves, known as whispering-gallery waves, that travel around the circumference clinging to the walls, an effect that was discovered in the whispering gallery of St Paul's Cathedral in London.

However, while the charges are clearly heart-shaped, they did not depict hearts in origin, or symbolize any idea related to love.

Earlier historians have posited that the earliest lingling-o artifacts found in the Philippines were created outside of the archipelago, but an expedition to the northern Philippine province of Batanes, led by archeologist Peter Bellwood in the early 2000s, led to the discovery of a lingling-o workshop, complete with construction tools and fragments.
