Founder (In Memoriam)



 

Colin G. Gordon

Short Biography

Colin Gordon (1934-2005) founded the firm that bears his name in 1990 and worked in the field of acoustics research and noise and vibration for over thirty-five years. Twenty years were spent with the firm of Bolt Beranek and Newman (BBN), the firm largely responsible for developing the engineering science of acoustics between 1950 and 1970. Five years were spent with the Institute of Sound and Vibration Research (ISVR) at the University of Southampton.
In his last twenty years, the microelectronics industry was a key area of focus, with the design of low-vibration facilities for the research and fabrication of integrated circuit "chips". Colin developed a strong and unique reputation in this specialized field. Colin was widely recognized within the microelectronics industry for his contributions to the understanding of the vibration and noise environments of technology buildings. He pioneered many of the now-common analytical approaches to floor design and the analysis of noise and vibration from ducting and piping. He was co-developer (with Eric Ungar) of the widely-used vibration criteria for vibration-sensitive facilities. He had mentored many of the current generation of vibration consultants in this field.
