REFERENCES ON RESEARCH
Another way of disseminating knowledge in the field of acoustics is by performing research. Level Acoustics has been working on several research projects for manufacturers and developers of acoustical products. This has been done either inside or outside the laboratory. Besides that, laboratory and field research is often integrated in consultancy projects. Some examples of recent projects are found below:

Research projects on Room Acoustics
- Volkskrant, measurements of speech privacy
- NAC Breda, sound transmission between soccer supporters
- Studio l'Équipe, comparison study of two Foley Studios
- Nederlands Philharmonisch Orkest, orchestra pit sound levels
- Acoustics Engineering, sound source certification program
- Qatar Education City, library scale model 1:32

Research projects on Building Acoustics
- Unifloor, new acoustics laboratory design
- Schiphol design contest, the sound insulation of water
- Eindhoven University of Technology, environmental noise
- Wienerbergen, advanced sound insulation predictions

Airborne Sound Insulation
- Espero movable panels (development of new wall)

- Van Keulen, silent roads

Sound Reduction Index Kij of junctions
- Xella, calcium silicate blocks junction
- Slimline Buildings, development of lightweight junction

 

  Room acoustical measurements
  are performed with a omni-
  directional sound source.
 

  Walking Noise is measured in the
  laboratory using a tapping machine.
 

 

 

  The sound reduction index of a
  calcium silicate blocks junction is
  measured in a laboratory setup.
