Charles Hughes is currently the principal engineer for electroacoustics at Biamp Systems. Previously, he was the principal consultant at Excelsior Audio, during which time he also worked for Ahnert Feistel Media Group (AFMG). Mr. Hughes has been involved in the design and measurement of loudspeaker systems for 35 years and a member of the AES since 1994. He is a graduate of the Georgia Institute of Technology with a BS Physics degree. Prior to starting Excelsior Audio, he was employed as a loudspeaker design engineer by Peavey Electronics and Altec Lansing.

One of Mr. Hughes' primary areas of interest is the directivity control of radiation from loudspeakers and loudspeaker arrays. He has designed scores of horns in conjunction with this endeavor as well as becoming very involved with loudspeaker modeling and simulation. Five US patents have been issued to him as a result of his work and designs in this area. He holds two other US patents related to noise cancellation.

Mr. Hughes is an active member of the AES with a keen interest in standards development. He is an active participant of multiple AES standards committees, currently serves as the vice-chair of SC-04-03, and was heavily involved with the recently published AES75 standard. He has authored or co-authored multiple AES papers, has been an invited panelist at several Live Sound Seminars and Workshops at numerous AES conventions, including chairing one on subwoofer array directivity, and been invited to lecture at local AES section events. Additionally, his technical articles have appeared in numerous industry publications.

Mr. Hughes also serves as moderator for the AVIXA Spectral Balance standard committee and formerly chaired the Consumer Technology Association standards group CTA R3 WG1. During his 15 year tenure there ANSI/CTA-2010, ANSI/CTA-2034, and ANSI/CTA-2099 standards were published. As a result of his work, he received the 2013 CTA Technology Achievement Award.
