Double wall and double floor constructions for obtaining the permitted noise levels in studios

摘要

Many permitted noise levels for studios are well known and in practical use fordifferent types of studios and control rooms. They are strict and difficult toreach. Disturbing noise originates from adjacent studios or from outside thebuilding. Acoustical measures are related to building constructions and singleelements such as windows, doors or suspended ceilings. The different soundpaths can be described to evaluate their contribution to the overall soundinsulation. Double wall and double floor constructions are important fordamping the sound radiation from the surfaces. Constructions will be describedand measurement results are included.Building defects lead usually to disadvantages for the use of studios.Restrictions are inevitable. The costs for repairs blast the expectations.Therefore, very careful craftsmanship is required. It should be emphasized thatthese studio constructions are used in many other situations as well, e.g.theaters, music schools or high quality apartments.
