DEGA recommendation 103

from Wikipedia, the free encyclopedia

The DEGA recommendation 103 Noise Protection in Housing Construction - Noise Protection Pass is a publication of the German Society for Acoustics e. V. (DEGA). It was drawn up by the Building and Room Acoustics Committee and published in March 2009.

concept

The two main objectives of DEGA Recommendation 103 are:

  • Creation of a multi-level system for the differentiated planning and marking of the structural sound insulation between room situations regardless of the type of building ,
  • Development of a point system on this basis for the simple identification of the sound insulation of entire residential units or buildings .

The system is tailored to the construction methods customary today and to the current minimum requirements according to DIN 4109 introduced by the building authorities . By division into a total of seven stages a differentiated and practical classification is used both for new buildings and for existing buildings allows.

Unfortunately, the technical parameters of noise protection are very difficult to understand and understand for planners and users. In other areas (e.g. energy saving in buildings or electrical appliances), it has been possible to create transparency for consumers in a simple manner through evaluation systems and labeling. This transparency was created with the DEGA recommendation and the noise protection certificate in the area of ​​structural noise protection through a building-independent evaluation system.

background

Example of a noise protection pass

The first DIN standard in which the level of sound insulation required by building law was laid down is the DIN 4110 standard sheet published in 1938; a first version of the standard sheet DIN 4109 "Sound insulation in buildings", which is still relevant today, was published in 1944. This fundamental work is the basis of structural noise protection in Germany and was also a model for comparable standards and regulations in neighboring countries.

As explained in detail in the foreword of DIN 4109, the minimum sound insulation stipulated there was always seen to prevent unacceptable noise pollution in normal living behavior. In terms of today's user demands, user behavior and way of life, this is often not sufficient, and at least in some areas it could be carried out much better at almost no cost. Nevertheless, with a few exceptions, the requirements of DIN 4109 still apply as a generally recognized rule of technology.

In order to meet the requirements of planners and users who want more than just minimum sound insulation, recommendations for increased sound insulation were already given in the version of DIN 4109 from 1962. In supplement 2 of the DIN 4109 from 1989, which is valid today, recommendations for increased noise protection can also be found. However, the values ​​there are so strongly influenced by compromises that the recommendations for increased noise protection differ only slightly from the requirements of DIN 4109 and there is therefore no subjectively significant improvement.

Due to the sensible and practical grading of the noise protection classes in DEGA recommendation 103 and with the help of the verbal descriptions contained therein, which are also understandable for laypeople, increased noise protection can be assessed and specifically agreed.

The DEGA recommendation 103 includes the DEGA noise protection pass. With the help of a point system, various acoustically relevant criteria are assessed and, as a result of the assessment, a total number of points and a class (F to A / A *) are determined for a residential unit , which then describes the acoustic quality of the residential unit. The evaluation system of the DEGA recommendation 103 includes the evaluation of the location and external noise as well as the structural noise protection. Here, both the sound insulation between other residential units and in one's own living area is considered.

In addition to DIN 4109, which is binding under building law, and DEGA recommendation 103, there is also another building acoustics guideline in the form of VDI guideline 4100. This provides different guide values ​​for noise protection in private residential construction.
