Many permitted noise levels for studios are well known and in practical use for different types of studios and control rooms. They are strict and difficult to reach. Disturbing noise originates from adjacent studios or outside the building. Acoustical measures are related to building constructions and single elements such as windows, doors or suspended ceilings. The different sound paths can be described to evaluate their contribution to the overall sound insulation. Double wall and double floor constructions are important for damping the sound radiation from the surfaces. In this paper constructions are described and measurement results are included. Building defects usually lead to disadvantages for studio use. Restrictions are inevitable. The costs for repairs blast the expectations. Therefore, very careful craftsmanship is required. It should be emphasized that these studio constructions are used in many other situations as well, e.g., theaters, music schools or high-quality apartments.:
