Klippel's Near-Field-Scanner 3D (NFS) offers
Klippel's Near-Field-Scanner 3D (NFS) offers a fully automated acoustic measurement of direct sound radiated from the source under test. The radiated sound is determined in any desired distance and angle in the 3D space outside the scanning surface. Directivity, sound power, SPL response and many more key figures are obtained for any kind of loudspeaker and audio system in near field applications (e.g. studio monitors, mobile devices) as well as far field applications (e.g. professional audio systems). Utilizing a minimum of measurement points, a comprehensive data set is generated containing the loudspeaker's high resolution, free field sound radiation in the near and far field.
I use the NFS for my measurements and planned to create a video discussing it and how it is used. However, rather than me attempting to explain the science behind it, Christian Bellmann - one of the brilliant minds behind the NFS - joins me to provide insight in to the design and workings of the NFS.
Christian was born in Freiberg, Germany, in 1987. He studied mechatronics in Dresden University of Technology with the focus on control engineering, power electronics and electrical drives. In 2013 he received a Diploma degree for his thesis “Separation of direct sound and room reflections using holographic methods” which was supervised by Dresden Technical University and the Klippel GmbH in Dresden. After his graduation, he joined the Klippel GmbH where he is currently engaged in the research and development of loudspeaker measurement systems with focus on acoustical holography.
