On July 19, 1951, workmen were cutting and installing one-inch blankets of insulation in the band room at the new chapel-music-speech building at Pacific Lutheran College. The J-M system of sound isolation was being used to control sound waves which are transmitted by structural vibration. Light weight and specially constructed floors, walls and ceilings were entirely divorced from the building structure by means of felted isolators. The floating interior had no rigid contact with the outer solid structure of the building. The felt cushioned isolators took up the sound impulses which otherwise would be transmitted throughout the structure. (TNT, 7/22/1951, p.C-12)
