ACOUSTIC TEST FACILITIES
>> AEROACOUSTIC WINDTUNNELS
................................................................................................................................................................................................................................................................................
Wind tunnels reproduce the various aerodynamic and
aeroacoustic phenomena which vehicles are subjected to, offering modern,
effective testing resources to help engineers cut fuel consumption and
improve safety.
Aeroacoustic wind tunnels provide uniform wind conditions, similar to
pure aerodynamic wind tunnels except that the background noise levels
are reduced in order for the wind noise to be correctly measured without
contamination.

Major noise sources like the air fan should be powerful and quiet at the
same time. The open jet stream in the test section can create an even
higher noise level so a carefully design must combine a sufficient
aerodynamic situation with an excellent acoustic performance. In order
to achieve free-field conditions, both our PK CAR-System and the PK
wedge type system can be applied. |
