Introduction
The musical instruments innovation pole activity is divided in 4 axes : - Technological transition - Ecological transition - Cultural heritage - Entreprises support We perform reseach, transfer and training courses for musical instruments makers. Currently, our topics are the development of materials for substitution of tonewood, the creation of an e-learning platform for instrument making, the development of affordable characterization tools and the promotion of technological devices.

Early in the CoViD-19 pandemic, musical practices, especially singing and playing wind instruments, have been pointed out as having a high risk disease transmission due to aerosol production. However, characterization of these emission sources was not consolidated. This study focuses on the generation of aerosols and potential reduction in the cont...

This document aims to provide elements to instrument makers for their exploratory and experimental approaches. It exposes accessible concepts and methods, which allow to conduct experiments the best way to achieve consolidated results. This is a summary of the procedure to follow - and not to follow - when we want to observe / ascertain a phenomeno...

Ce document vise à fournir des éléments aux facteurs d'instruments pour leurs démarches exploratoires et expérimentales. Il expose des concepts et des méthodes accessibles, qui permettent de conduire au mieux des expériences pour consolider des résultats. Il s'agit d'un résumé de la démarche à suivre -et ne pas suivre- lorsque que l'on veut observe...
Article
Full-text available
It is generally alleged that the design choices of acoustic guitar bracing patterns lead to a specific sound of the instrument. However, in the presence of strong uncertainties due to variability of material properties and climatic conditions, the robustness of the soundboard dynamics has yet to be investigated. In this study, three types of bracin...
Article

Nowadays, the virtual prototyping method is widely used for industrial applications and can lead to a powerful tool for musical instruments making and conservation. Nevertheless, physics-based models of musical instruments are barely developed for this purpose and the confrontation between model predictions and experiments have been the focus of ve...
Article
Full-text available
The tonewoods used in musical instruments are finely selected and are subject to current and upcoming availability issues. Wood grading assesses the quality of the tonewood and depends on both subjective and objective criteria. Traditionally, grading criteria based on mechanical properties consider mainly the longitudinal direction. This paper inve...
Conference Paper

In this study, a finite element model is used to simulate the impact of wood modifications on the dynamical behaviour of a violin. Chemical and fungal modifications of the wood selected for violins (tonewood) are considered. In addition, the impact of spruce indented rings anatomic singularities is also studied. Models are used to compute modal bas...

Thesis
Full-text available
This work proposes a methodology for the transfer of industrial and research domain methods toward arts and crafts domain. The virtual prototyping and mechanical characterization of materials are used for the stringed musical instruments making domain. The studies are addressed to the guitar and violin making. This domain is historically driven by...

This poster sums up the current works on the eplacement of traditionnal wood species by natural fibres composites. A numerical model is used to optimise composite layers orientation and core thickness
Article
Full-text available
Inverse methods have been used for decades to identify material properties, in parallel, or as a substitution for direct methods. Although it has proven a useful method for many types of materials and simple geometrical shapes, it has barely been used on complex shape parts. This is the main objective of the non-destructive method proposed in this...

L'évolution et la diversification des procédés de fabrication et de mise en forme des matériaux composites permettent d'accéder à des objets ou des pièces de structure dont la géométrie est de plus en plus complexe. La détermination de leurs propriétés constitutives est généralement destructive et fastidieuse. L'utilisation de méthodes d'identifica...

The behavior of stringed musical instruments have historically been investigated primarily through experimental studies and simplified analytical models. In this study, a physics-based model of a violin is used to determine the most influential design and environmental factors impacting its vibrational behavior. A global sensitivity analysis is per...

Les études d’acoustique musicale se basent historiquement en grande partie sur des approches analytiques et expérimentales. Ces approches s’avèrent représentatives de la réalité mais ne sont pas nécessairement les mieux adaptées pour étudier l’impact de modifications de conception d’un instrument. Le prototypage virtuel basé sur les modèles physiqu...

Plant fibers are increasingly used in wide ranges of applications. They are particularly good candidate to be used as composite reinforcements for lightweight structural applications. Their fatigue and dynamic behaviors, and their evolution under varying environmental conditions and ageing are a high stake topic in both research and industry sector...

Luthiery is a secular art of craftsmanship, consisting in the selection of the best pieces of wood chosen for their texture, tone, and appearance. These pieces are then carved and assembled according to traditional methods, transmitted from master to apprentice. Instrument makers, as well as scientists, have always been interested in the complex vi...

Résumé : L’identification de paramètres par mesure de champs présente plusieurs intérêts tels que robustesse, répétabilité des mesures, non-destructivité et non-invasivité de l’essai ; tout en fournissant un nombre important d’informations pour un temps d’essai et de mise en place rapide. Les essais ont été menés sur des éprouvettes de bois, avec p...
