Using ‘laser Doppler vibromety’, a 3D computer model and lasers to map the vibrations as the bells chimed at 9, 10, 11 and 12 o’clock, the team were able to characterise the distinct sound and map the vibrations in the metal of Big Ben that are too tiny to be seen by the naked eye. And the results? As it is thicker and weighs more than other bells of a similar size, the result is a higher pitch than would normally be expected for its diameter. Big Ben and the four quarter bells are set to resume sounding the famous daily ‘Westminster Quarters’ melody and resonant bongs using the original mechanism in Spring 2022.
