This study examines a rarely considered acoustic consequence of the piano hammerโstring collision: the direct sound produced by the hammerโs rapid acceleration at impact. Using analytical methods and 2D finite element modelling, the resulting acoustic pressure is simulated and combined with the synthesised responses of a stiff string and soundboard radiation. The composite signal is analysed...

The accordion is a type of free-reed instrument. In this instrument, a pitch bending technique can be performed where a player achieves a decrease in pitch up to a semitone or so by partially pressing a key while operating the bellows forcefully. The mechanism of accordion pitch bending is fundamentally different from that of the harmonica. While the latter is caused by the player's vocal...

This paper investigates the substitution of traditional ribbed piano soundboards with an equivalent single-ply structure while preserving key acoustical and mechanical characteristics. Piano soundboards play a crucial role in sound radiation, inter-string coupling, and overall tonal quality, all of which are strongly influenced by geometry and material properties. With the decreasing...

4121. Low-frequency dissipation of a musical string in a viscous fluid: numerical study (FA2026/930)Antoine Hajczak (Sorbonne Universitรฉ, CNRS, Institut Jean Le Rond d'Alembert)09/09/2026, 09:20A11 Musical Acoustics
The distinct sound of a string instrument depends on harmonic attenuation. While past studies have mostly focused on high-frequency thermoelastic damping, we investigate here low-frequency dissipation in a real (viscous) fluid. Todo so, we solve the incompressible Navier-Stokes equations using Basilisk, a finite volume solver capable of handling adaptive octree meshes around moving bodies with...

Modal synthesis is a widely used technique for simulation of musical instruments. In the linear case, a modal decomposition leads to an uncoupled system of damped and forced harmonic oscillators which can be efficiently solved by regular time-stepping methods. However, extensions to nonlinear problems are challenging due to the presence of products of modal expansions in the governing...

The function of bowed string instruments has been a subject of research since the times of Helmholtz and Raman. However, the characteristics of the frictional interaction at the bow-string interface have evaded researchers for several decades. Taking the rapid temperature variations during stick-slip motion into account was deemed necessary in order to obtain an accurate model of bow-string...

An energy-balanced linearly implicit scheme for aclass of systems including nonlinear dissipation lawsis proposed. It is based on previous work on virtualanalog simulations and bowed string simulations, andallows an efficient update. Specifically, the scheme isgeared towards real-time synthesis of reed instrumentsand voice.In order to include conservative nonlinearities (derivedfrom a...

A direct numerical solution of the Navier-Stokes equations was used to obtain the time dependence of the pressure and air velocity in and around a recorder as it produced a musical tone. A Helmholtz decomposition was then applied to extract the irrotational and solenoidal components of the velocity. The simulations also yielded the Lamb vector, allowing a comparison with predictions for the...

Rosettes covering the sound hole are characteristic of traditional Greek long-necked string instruments such as the Cretan lute. Although rosettes are known to influence the resonance of musical instrument cavity, their vibrational and airflow effects remain insufficiently studied. This work numerically examines 27 typical Cretan lute rosette geometries using finite element modal and...
