TL;DR: This work imagines two kinds of devices allowing us to deduce the size of the raindrop from impact forces, considering natural parameters such as drop radius and density, impact speed and response time of the substrate.

High-resolution modal analysis
TL;DR: In this paper, a high-resolution analysis algorithm and an order-detection method are presented to fill the gap between the low and the high frequency domains (30% < mu < 100%).

Damping by branching: a bioinspiration from trees
TL;DR: A new damping mechanism inspired by the architecture of trees is identified and characterized in the simplest tree-like structure, a Y-shaped branched structure, showing significant levels of damping achieved via branching with typically 30% of the energy being dissipated in one oscillation.

Vibroacoustics of the piano soundboard: (Non)linearity and modal properties in the low- and mid-frequency ranges
TL;DR: Ege et al. as discussed by the authors measured the nonlinear part of the soundboard response to an external excitation at ≈ − 40 dB below the linear part at the ff nuance.

Numerical and experimental modal analysis of the reed and pipe of a clarinet.
TL;DR: Computed eigenmodes of the whole system show that modal patterns of the reed differ significantly whether it is alone or coupled to air, and suggests revisiting the customary quality index based on the alignment of the peaks of the input acoustical impedance curve.
