Lärmbekämpfung

Off-roading, for example driving on forest or rural roads, on offroad parks or military training grounds, are often facility-related noise that must considered when assessing noise exposure according to TA Lärm. The RLS-19, which is to be used for...

Metal cushions offer a chemically and thermally resistant alternative to elastomers. Their elasticity and damping are based on wire segment interactions, which also influence the electrical properties. This effect enables a new function- integrated...

The Environmental Noise Directive and thus also the Federal Immission Control Act (BImSchG) require public participation in preparation for noise action planning. Regularly, only a few people take advantage of this opportunity. With the help of...

Noise is described by institutions such as the Federal Environment Agency as an “environmental disease burden” for humans, the severity of which directly follows that of particulate matter [1]. Even at low sound levels, just above the hearing...

For the immission control assessment of noise, the A-weighted equivalent continuous sound pressure level caused by a type of noise source to be assessed at the location in question is determined for specified assessment times. In the case of...

The question „it is (subjectively) too loud“ is countered by the need to assess the situation objectively and in a legally secure manner using a sound pressure level meter. Ultimately, a measured value should be able to be compared with the...

The sound power level is the most important parameter for describing the noise emission of machines and other products. It must therefore be possible to determine it with the least possible effort by means of standardised measurement procedures...

Acoustical comfort normally requires a profound design planning and elaborate structural measures in rooms. Both are usually carried out by specialists and rarely in a do-it-yourself manner. Both the planning and the implementation of the measures...

Suspended ceilings have an impact on sound insulations as well as on room acoustics. The suspension height, meaning the space between room ceiling and suspended ceiling, is an important parameter which influences both acoustical effects. According...

The development of speech intelligibility tests began over 80 years ago, originally for the needs of telephone technology. The initial aim was to test the quality of electro-acoustic transmission systems and routes. The indicator for this was the...

The poor room acoustics situation in many educational institutions has been criticized for years and has been the reason for the revision of the room acoustics standard DIN 18041 on several occasions. This is not only about speech intelligibility...

The version of DIN 4109 – Sound insulation in buildings – introduced under building law only lists average sound pressure levels as a parameter for determining sound insulation in its requirements for sound insulation against external noise,...
