DEPARTMENT OF ACOUSTICS AND BUILDING PHYSICS
Our field of activity
Acoustical measurements and calculations with the following focal points:
Testing of the sound insulation of building components
Testing the sound absorption of elements
Noise emission and immission measurements
Noise immission forecasts and assessments
acoustically relevant material tests
Measurements and calculations for room acoustics
Participation in research projects in the field of psychoacoustics
Testing of the sound insulation of building parts
It is investigated how much sound caused by e.g. B. a window, a wall, a door or a ceiling passes through.
Standard test stands are available to determine the airborne sound insulation.
These each consist of two rooms, between which the test object is installed. Loud noise is then generated in one room and the sound level is measured in both rooms at the same time. If necessary, the measurement of the sound level difference can also be carried out with a component installed in the building.
Noise emission and noise emission
It is investigated how loud a sound source (e.g. machine is) and / or how much noise arrives at a position to be protected (e.g. apartment).
The sound emission of a sound source can be measured at its installation location or in our anechoic room. We also measure the noise immission, for example in front of a bedroom window, with calibrated measuring devices.
Room acoustics
The acoustic properties of a room are examined by measurement and improvement measures are worked out with computer models.
The acoustic properties of a room can be described by standard measurement of the reverberation time and other parameters, such as speech intelligibility.
In the computer model, it can be shown on which areas of the room, for example, sound-absorbing wall cladding is advantageous.
