Template:Mergeto The Logos Tetrahedron is a concert hall in Ghent, Belgium adjacent to the Logos Foundation recording studio and offices. It has seating for 150 people and is equipped with sound and light infrastructure. Since the concert hall is in the shape of a tetrahedron, it has no straight angles and, as a result, no standing waves can occur. Acoustic waves can never amplify one another in phase and are reflected by the walls under ever changing angles.
The hall is exclusively used for contemporary and experimental music, such as electronic music and computer music and holds approximately 65 concerts a year, mostly organized by the Logos Foundation.
The concert hall was built in 1990 by Godfried-Willem Raes and the Logos workgroup using steel, concrete and plate-metal. Construction took one year. The hall was opened in 1991 with a three day festival.
