Zusammenfassung: During 2021, the 200th anniversary of Hermann v. Helmholtz, a major activity was initiated by Leonardo Fuks to produce a number of new musical instruments that feature Helmholtz resonance effects. The idea of the collection was to feature the various concepts of resonance and perception that Helmholtz featured in his publications, including "On the sensations of tone". A part of this production and testing took place during his visit at the Erich Thienhaus Institute at Detmold University of Music using a 3D printer and manual production techniques. Acoustic analysis methods such as overtone and impedance measurements on the instruments demonstrate the validity and limitations of the idealised resonator models. Within the structured session the instruments will be displayed, their features will be characterised by measurements, and a set of instruments will be available for playing live at an exhibition booth, if possible.
