The AES recognizes and honors those who have made outstanding
contributions to the field of audio in engineering, technology,
service, and the arts through its Awards Program.
In 1991, Eberhard Zwicker was presented with the
AES Gold Medal Award for his career-long outstanding contributions to the science of hearing; in particular, for his research work on loudness perception, with the concept of "Frequenzgruppen" or auditory critical bandwidths and development of loudness measuring devices, for his discovery concerning temporal auditory processing, for his physical model of cochlear hydrodynamics, and for his work with cochlear transplants.
