Authors
Benjamin Markham LEED AP is the Director of Architectural Acoustics at Acentech Incorporated Cambridge MA. Mr. Markhamas a consultant in room acoustics sound isolation and mechanical noise and vibration controlhas advisedarchitects and building owners on the design orrenovation of several hundred buildings from music facilities to classroom build ings and residential towers. He currently teaches architectural acoustics as a Lecturer at the Harvard University Graduate Schoolof Design; at the MIT Department of Architecture; and at the Cornell University College for Architecture Art and Planning.
Erie Ungar Sc.D. PE is the Chief Engineering Scientist at Acentech Incorporated Cambridge MA. Dr. Ungar has workedin the areas of vibration and noise structure-borne sound structural and machinery dynamics and stress analysis since 1958 recently focusing on facilities and buildings that acmodate extremely vibration-sensitive equipment or that require highresistance to vibration-related damage or malfunction. He previously taught machinery dynamics and applied mechanics at New York University and earlier participated in atomic weapons development at Sandia Coporation. A fellow and past president ofseveral professional organizations he is a recipient of the Gold Medal for Noise Control and Acoustics of the American Societyof Mechanical Engineers and of the Gold Medal of the Acoustical Society of America.

Preface
This Design Guide provides guidance for achieving suitable acoustical environments in steel buildings. The control of soundtransmission must be considered for every building under design This Guide will provide a discussion of the issues involved andthe tools avalable to assthe desiger seleting appropriaeassemlies to addresound transmission in stee-frad bid ings. A Glossary is provided at the end of this Design Guide to define terms that may be unfamiliar to the reader.
