Abstract
- In 2013, a new draft of a complete standard for DIN 4109 "Soundproofing in buildings" was issued in 4 parts - "Requirements", "Method of calculation", "Parts catalogue" and "Testing acoustics in buildings". It includes several increases in the requirements for protection against airborne noise and impact sound by comparison to DIN 4109:1989. The increases are based on the grades from monitored buildings of standard construction periodically noted in recent years. Significant changes are also included in Part 2 "Input data for verifying the requirements by calculation". A detailed computation of all transmission paths is carried out here, taking into account the special vibration reducing indices. For a brick wall, the specific indices for the weighted sound reduction index R'<subscript>w,R</subscript> are shown that arise for various formations of the joints. When compared with the calculated values according to DIN 4109:1989 there are differences of up to 10 dB. [ABSTRACT FROM AUTHOR]
