Quantifying microphone array directivity: The quantification and improvement of the acoustic camera of the TU Delft

The sound of fly-over aircraft is measured with the use of an acoustic camera to gain more information on aircraft noise. This camera can be optimised to gain data of a higher quality. Within the ANCE section this optimisation was required mainly to diminish the influence of the ground effect in the data and to increase the resolution of the...

Acoustic Array Design: The design of a reconfigurable phased microphone array for aeroacoustic wind tunnel measurements

Since both the aircraft and wind energy sectors are experiencing rapid growth, improvements must be made in terms of noise reduction as to enable growth whilst fulfilling the restrictions on noise pollution. An open-section vertical wind tunnel with an anechoic test chamber has recently been constructed at the Delft University of Technology, in...
