Plenty of normative handle too high noise impact at work, either in offices, factories or similar, in order to limit stress, increase productivity and for health protection. For private homes, struc-tural acoustics becomes regulated, concerning air borne and tapping noise transmission plus noise from the outside. Private homes are not subject to limitation of noise, produced by residents in their own rooms. After a working day full of effort, you are looking forward to a home to recover. In many cases, however, self-produced noise inhibits to relax. There is a remarka¬ble difference in the acoustical quality between “grandma’s living room” and a de-signed modern eat-in kitchen plus large living room. Sound reflecting surfaces, large windows, designed furniture and big volume result in a noisy home. In contrary to that, in a room full of curtains, carpets and thick upholstered sofas the acoustical comfort is higher. This case study shows both, a noisy home and a silent one. The acoustical effect of an invisible technical solu-tion and an approach to reduce sound transmission through an open staircase for private homes are presented.
