An acoustical ceiling now floating above Rocky River High School’s newly renovated media center and library on Cleveland’s west side is the work of Roger Kreps Drywall & Plastering Co.
Want to understand the importance of how a ceiling can help absorb sound in a room? Consider the Amsterdam University Medical Center and its Emma Kinderziekenhuis Children’s Hospital.
A relatively inexpensive hobby of mine is the collecting of old technology books. My collection includes books on rebuilding player pianos, blacksmithing and a mail order course on how to set up a vacuum tube radio repair shop (I will be set if my time machine leaves me stranded in the 1850s or 1950s).
