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, Michael A. Gerzon was presented with the
AES Gold Medal Award for over 20 years of continuous development of the theoretical basis of surround-sound reproduction systems in general and of the means to realize them in practice; in particular, the award honors his outstanding contributions to the theory, analysis, and design of the Ambisonic surround-sound system and of the soundfield microphone.
