The need to keep long wind musical instruments compact imposes the bending of portions of the air column. Although manufacturers and players mention its effects as being significant, the curvature is generally not included in physical models and only a few studies, in only simplified cases, attempted to evaluate its influence. The aim of the study is to quantify the influence of the curvature both theoretically and experimentally. A multimodal formulation of the wave propagation in bent ducts… 
Physical Modelling and the Associated Acoustic Behaviour of Trumpets and Trombones
Accurately modelling the production of realistic musical notes in brass instruments is no easy task. Compared to woodwind instruments, brass instruments are considerably longer and constructed with
Wind Instruments: Variable Cross Section and Toneholes
Wind instruments are studied in two steps. In the first step, one-dimensional models are presented. The horn equation is equivalent to the heterogeneous string studied in Chap. 3 It can either be
Computational Acoustic Methods for the Design of Woodwind Instruments
This thesis presents a number of methods for the computational analysis of woodwind instruments. The Transmission-Matrix Method (TMM) for the calculation of the input impedance of an instrument is
Finite Element Modeling of Woodwind Instruments
The input impedance of simple woodwind-like instruments is evaluated using the Finite Element Method (FEM) and compared to theoretical calculations based on the transmission-matrix method (TMM).
Extensions to the Mode Matching Method for Horn Loudspeaker Simulation
TLDR
The Mode Matching Method is extended to new cases closer to real-world applications, and the use of the method to compute the transfer function and resonance frequencies of non-shoebox shaped rooms is used.
Theoretical and experimental study of vocal tract acoustics
The vocal tract acoustics is often described witha simple one dimensional plane wave approach.However, this is not satisfying when at high frequency(from about 5 kHz) three dimensional variations

Speed of Sound in Bent Tubes and the Design of Wind Instruments
TRUMPETS, bassoons and other long wind instruments are made with bends for compactness. They would function best if each bend behaved acoustically just like a definable segment of straight tube. The
INFLUENCE OF A TOROIDAL BEND ON WIND INSTRUMENT TUNING
In a toroidal bend in a cylindrical wind instrument, with the same cross section as the cylindrical part, the inertance for longitudinal waves is reduced. This induces a change in the resonance

Sound propagation in rigid bends: a multimodal approach.
TLDR
The sound propagation in a waveguide with bend of finite constant curvature is analyzed using multimodal decomposition, showing the importance of higher order mode generation at the junction between the bend and the straight ducts.
Corrections to the Plane-Wave Approximation in Rapidly Flaring Horns
The input impedance of an air column (horn) with a slowly varying cross section can be calculated approximately by solving the wave equation assuming plane waves (Webster equation). In some cases
