This paper will discuss the background and history of "laminated steel" (commonly called "noiseless steel" or "MPM". It will provide the early development, where it came from and how it was introduced to North America as a new tool for engineering acoustical solutions. A progressive timeline will show laminated steel from its earliest inception and application in Europe to its current role in today's global market. Case histories along with examples of successful applications will detail its important contribution in advancing the technology for component damping. Many manufacturing sources as well as end-users have been impacted over the the decades since it was introduced. Many of these companies will be highlighted.The background information for this paper is provided by many of the individuates who were involved in the very early stages of its introduction as well as those who are currently working to utilize the technology of "laminated steel".
