Feedback form is now closed.
Supporting instrument makers on an innovation strategy, the innovation hub of the Institut Technologique Européen des Métiers de la Musique (Itemm) develops tools to predict the acoustical behavior of wind instruments. From the entire internal bore profile including holes and pistons, the PAFI online platform provides features such as the input impedance or the acoustic pressure or velocity along the bore. The input impedance provides the resonance frequencies which are linked to the playing frequencies (with a musician). The difference between the two is partly due to the coupling between the musician and the mouthpiece. In order to determine this difference a series of measurements carried out on different instruments such as flutes or brass instruments are made. Comparisons between played frequencies and measured resonance frequencies are presented on those different instruments types. Comparisons between measured resonance frequencies and calculated resonances frequencies from the bore profile of the instruments are also presented. This information is intended to help instrument makers to estimate playable frequencies from measured or calculated resonance frequencies.
