A statistical analysis of the results reveals good correlations, but also significant differences between both series. Within a given series, flexural modes are not strongly correlated. A Principal Component Analysis (PCA) shows that the measurements of each series can be described with 3 factors capturing more than $90\%$ of the variance: the first is linked with transverse modes, the second with flexural modes of high order and the third with the first flexural mode. A forth factor is necessary to take into account the individual sensitivity to moisture content. Numerical 3D simulations are conducted by Finite Element Method, based on a given reed shape and an orthotropic model. A sensitivity analysis revels that, besides the density, the theoretical frequencies depend mainly on 2 parameters: $E_L$ and $G_{LT}$. An approximate analytical formula is proposed to calculate the resonance frequencies as a function of these 2 parameters. The discrepancy between the observed frequencies and those calculated with the analytical formula suggests that the elastic moduli of the measured reeds are frequency dependent. A viscoelastic model is then developed, whose parameters are computed as a linear combination from 4 orthogonal components, using a standard least squares fitting procedure and leading to an objective characterization of the material properties of the cane \textit{Arundo donax}. %G English %2 https://hal.science/hal-00668277v2/document %2 https://hal.science/hal-00668277v2/file/taillard_12.pdf %L hal-00668277 %U https://hal.science/hal-00668277 %~ ENS-PARIS %~ UPMC %~ LKB %~ CNRS %~ UNIV-AMU %~ UNIV-LEMANS %~ LMA_UPR7051 %~ ALLINSP %~ EC-MARSEILLE %~ L2C %~ PSL %~ UPMC_POLE_2 %~ MIPS %~ UNIV-MONTPELLIER %~ LAUM %~ SORBONNE-UNIVERSITE %~ SU-SCIENCES %~ ENS-PSL %~ SU-TI %~ ALLIANCE-SU %~ UM-2015-2021 %~ PEIRESC
