High sound levels were anticipated in the bar, continuing late into the night in this newly revitalized neighborhood of Lower Downtown Denver. A heavy ceiling was designed and supported by a spring suspension system. A separate spring-isolated structure was created for the bar. Acoustical vinyl was used under carpet in the guestrooms. The audio system was designed for noise control capabilities. Comments and photographs will show elements of design and construction. The result is that airborne sound transmission is not a problem between this new restaurant and adjacent guestrooms.", }
