The Vox Maris ("Sound of the Sea")[1][2] is an instrument that was built for the Yeosu Expo 2012 in Korea by the German organ building company Hey Orgelbau (de)[3][4][5] and was recognized as the acoustic signet of the exposition.[2][6] It combines elements of the pipe organ and the steam whistle. The Vox Maris entwines itself around the twin sky towers at a height of 72 metres (236 ft).[7] It is considered an aerophone, since its dynamic high pressure organ pipes are powered by air. It can be played from a wireless tablet-pc.[8]
The construction process was documented by a film team of German Bavarian Television.
On 21 October 2011, Guinness World Records confirmed the Vox Maris as the loudest pipe organ in the world, producing a reading of 138.4 dbA.[3][7][9]
In 2015, the RID (Rekord-Institut für Deutschland) corroborated the Vox Maris as the loudest pipe organ.[8]
