Laborprotokolle der diesjährigen TeilnehmerInnen über die durchgeführten Messungen.
Messungen mittels Kugelmikrofonarray

Lab documentation from Stefan Lösler, Uwe Neugebauer, Florian Pausch concerning measurements with a 64 channel surrounding spherical microphone array for holography of sound-radiation. Measured objects were a stage monitor box and the IEM icosahedral loudspeaker.

Messungen mit ebenen Mikrofonarrays

Lab documentation from Sebastian Braun, Antonio Hölzl, Herbert Petritsch describing measurements with planar microphone arrays for acoustic holography. Measured subjects were: the wave-field originating from a loudspeaker and the acoustic near-field of a wire clothes-hanger.

Messung von Abstrahlcharakteristika mittels Halbkreis-Mikrofonarray

Lab documentation from Rudolf Liepins and Andrés Ureta about measuring the directivity of sound sources with a hemispherical microphone array and a truntable. Measured subjects were the directivity of a stage-monitor box and the spherical harmonics radiated by IEM icosahedral loudspeaker.

Messung mit ebenen Mikrofonarrays (Teil1: Wellenzahlspektrum)

Lab documentation from Felix Bissardella and Philipp Schmidt about measurements with a planar 64 channel microphone array and the acoustic k-space decomposition. Measured subject was the field of a loudspeaker at the array, decomposed into the k-space, showing the effect of spatial repedtitions and aliasing.
