Eberhard Zwicker

Karl Eberhard Zwicker ( born January 15, 1924 in Öhringen, † 22 November 1990 Icking ) was a German professor of acoustics and electro-acoustics at the Technical University of Munich.

Eberhard Zwicker, son of William Zwicker high school teacher, graduated from the Technical University of Stuttgart physics and electrical engineering and later was an assistant to Richard Feldtkeller. In 1956, the Technical University of Stuttgart gave him the venia legendi electroacoustics. In 1967, he was Professor and Director of the newly created Institute of Electro-Acoustics at the Technical University Munich.

Zwicker was with Richard Feldtkeller author of the basic standard work in psychoacoustics: The Ear as a message recipient. This is about the laws of the context of auditory sensation and sound. The work is based on research and verification work, especially in the 1950s and 1960s and coined terms such as hearing threshold and frequency group.

Zwicker developed a method for calculating the volume level, which has been standardized as DIN 45631. According to him, the Zwicker tone is named.

Zwicker was married and has two children.
